@OP, Frank A. Clark said, "If you find a path with no obstacles, it probably doesn't lead anywhere." As you have succeeded in buying some fraction of Bitcoin, that is also how some hackers and scammers are looking forward to successfully hacking people's wallets, stealing their private keys and security phrases, and messing with their funds. That's to say, Bitcoin is really a valuable asset, and a lot of people are accumulating it every day, either by buying it just the way you did or by stealing it through some scamming means. @Maus0728 has talked about your security, but you can also read these and these if you have time.

Well said. There is no problem in holding Bitcoin on any reputable exchange, as it gives you exposure to day-to-day price changes, but you don't fully own the Bitcoin. As you accumulate more Bitcoin it becomes increasingly important to consider self-custody options for greater control and protection of your precious asset. This may require investing in hardware wallet, but it is the most secure method to store Bitcoin.

That's true; people are afraid of missing out and are panicking and buying Bitcoin in an attempt to make up for lost time. As someone who entered the Bitcoin scene early but has only had a tiny amount since then, I can relate. However, you need to be cautious and set limits on how much you can afford to invest every week, month, etc. There's absolutely no reason to rush and attempt to compete with others; whether we like it or not, some users had a head start.

Exchanges, such as Binance or Bitstamp, are generally safe, and chances are that you'll have no issues with their services; they are also newbie friendly.

This is not a competition about who can bring as many bitcoins as possible so why rush and think of this as competition because indeed in this condition rush is also something that will indeed impact you later.
Thinking that is mature and doesn't need to be forced into something that is good enough to do in my opinion. DCA every week is very good but if we really can't do that then it's better to rearrange another strategy and maybe be able to do it in some good conditions or maybe once every month with the money you actually set aside.
Often times we see tons of people even creating threads about going into debt to buy bitcoins. I think even though it is their right, this can be categorized as one thing that hasty and actually gets them into trouble in the end.

This is an investment for the long term and currently there is still time to continue to add to the portfolio but this must also be adjusted to our conditions so we don't push ourselves too much.

Looks you are coming from Nigerian as your local currency used for investing in Bitcoin trough your deposit first by P2P, I am glad with your first time investing or purchasing Bitcoin and I think bigger fund based on my experienced. You were lucky from Nigerian because you have active local board in Bitcointalk forum and easy asking about anything when investing or step by step how to start deposit until withdrawing fund in cryptocurrency. First time I purchased or invested in Bitcoin under $5 with my local currency exchange still support trade under $5, but right now minimum trade or invested on Bitcoin and another altcoin have been $10.

You have been here in Bitcointalk forum more than one year and not bad with your first time investing in Bitcoin this year, I hope you will get profit and understand well with Bitcoin investment, many potential earn later become investor in Bitcoin or cryptocurrency.

I agree with everything you said Ryu_Ar1 - except that I felt that I needed to chime into your presumption that the employment of debt is going to lead to negative results.

I would agree with you that debt is likely an extra level of risk and brings complications towards a BTC investment that might not be needed; however, the employment of debt can also amplify returns if the debt is employed strategically and even with some luck.. so in some sense, you are correct that debt is not necessary, yet there are ways that debt can be employed in smart ways too.. and to bring greater riches to someone, even sometimes without necessarily devolving into gambling..

One of the problems that people have is to employ so much debt that they are not able to service the debt, and then they end up in a worse position because they employed the debt and something like BTC's price performance did not go as they expected.  On the other hand, if they have a multitude of ways to service their debt, and they are not relying on the BTC price to go up, sideways or to NOT go down (or to zero), they still could end up profiting way more from the employment of debt rather than if they had not employed such debt... so let's say that a person is constantly employing debt in order to make a variety of investments, and such person is investing into assets that s/he knows have very high odds of profiting within the timeline of the loan.. something like 80% of the time the loans return well above their expectations, and perhaps even within that 80% of positive performance, 10% of those are going to perform in 3x to 5x (or even more) of the performance of the other successful ones, so in that sense, the 80% positive performance (and perhaps 8% or so stellar performers) will more than make up for the 20% losers, and maybe even the losers are structured in such a way that they are NOT losing even 100% of what had been invested.. or they have various ways to structure limitations on their losses. 

So part of my point is that the employment of debt can add more complications, but the mere fact that there are more complications does not necessarily mean that they should not be done if someone knows how to structure such arrangements in a way that they are not gambling.. and they are quite likely to amplify profits.  So I would agree that amateurs and/or novice investors into bitcoin likely do not need to use these kinds of tactics, and they might not even have enough skills in order to be able to calculate both sides of the price performance possibilities, but it does not necessarily mean that they should not employ those kinds of strategies once they learn them and maybe even become competent with them, and it could take quite a bit of practice to build competence. .and even losing a few before such competence is built....

.... and actually I will agree with you on a side point that in recent times, we have seen a lot of very rich people and even seemingly very smart people get reckt as fuck because they were employing debt and leveraging processes in ways that went beyond their own competence or even that they had been failing/refusing to adequately/sufficiently account for various risks... and so very smart (and even experienced) people might get into products and debt arrangements in which they failed/refused to sufficiently/adequately account for the downside possibilities and repercussions.

Yes it is not a bad thing using exchanges as your wallet and it is more convenient to use, but then we should be careful and turn on all the authentication settings of that wallet. Maybe he should learn not to put too much money in an exchange for safety purposes only. Many people get hack because they failed to secure their money in an exchange or wallet. Hardware wallet can be useful too.

To setup a 2FA as soon as possible is also a must, it's true. However, in case the exchange itself scams their users, it won't make difference anyway, so it's really advisable he/she cashout the coins to a safe offline wallet before accumulating a considerable sum of money idle on the platform. This way he/she will be safe from potential third party hacking attempts and also from the potential event of being scammed by the exchange.

Congratulations on getting your first fraction of Bitcoin.  I hope the passion in you on accumulating Bitcoin won't die down.  I also hope you can withstand lots of selling temptations and holding frustrations. I also hope that you will not leave your Bitcoin in exchanges but rather keep it in your own wallet.  Remember, not your keys, not your coins.  And finally, I hope that this small steps will become huge enough to change your life for eternity.
