Welcome aboard! For newbies please always read and DYOR, especially for wallet and exchanges you are going to use, use regulated local exchanges in brazil (if there is any) it might good to buy there for your first set of bitcoins. Then explore for new ones.

Wallets to consider should be open source and trusted by many, if you're going to use some, always use google and search for its reviews on reddit or here in bitcointalk like "X wallet review reddit/bitcointalk" keywords, the same thing on exchanges.

Welcome, keep on reaching for that goal and we're all gonna be a millionaire someday. 
And with that $100 btc in you, don't stop accumulating and have more of it because the more, the better and the higher chance that you'll get to enjoy this run once bitcoin goes up for some more run maybe in next year or if you're planning to go long term in here.

Bitcoin is not a technology, it's simply Bitcoin and the technology is used for creating Bitcoin is blockchain that initiated from cryptography.

Welcome to the forum and become a bitcoin investor.

Of course, as a newbie you need to learn a lot before you want to continue your investment journey as well as to be able to make profits from the market and everything takes time, I hope you'll spend a lot of time catching up with other investors.


I just want to emphasize this so you understand better and I don't mean to disappoint you: bitcoin is not a tool to get rich quickly so it cannot help you turn 100 or 1000 dollars into millions of dollars. It is true that in the past bitcoin has increased in price by millions of percent and helped many people become millionaires with just a small amount of capital. But that is no longer true, bitcoin will still bring you significant profits if you invest strategically and can hold for the long term. As some people have said to become a millionaire, you need more than that $100 and you should keep investing every time you have money, don't just stop with $100 and dream about unrealistic things.

Most importantly, the market is a battlefield, it is extremely fierce and cruel. So always be alert in every situation, don't rush to easily trust anyone, even those who say they want to help you, scams are everywhere.

Better late than never.

Yeah, one day you will become a millionaire, but you need to know what you're doing.

If you want to turn your $100 become $1 Million, then you need to learn trading.

If you want to achieve $1 Million without trading, you need to spend a good amount of time and dedication since you need to work and invest, then repeat for many many years. But I'm sure you will achieve $1 Million using this way since it's the most safest.

Every single person I know of who thought they are too late ended up never purchasing Bitcoin and still hoping to catch up to the train.  They ended up losing an immense opportunity of making Money and they still would not acknowledge their mistake.

To be fair, no body knows where the Bitcoin Price will stop.  Will it rise forever?  Probably not.  The slowing down of percentages every 4 year Cycle speaks out loud.  So there is always this option that Bitcoin simply stops going up and either stagnates where it is or goes backwards.  But that applied back when Bitcoin never touched 20 thousand Dollars too, and most of the same people are STILL thinking it is late.

Well.  An opportunity to us, a lost one to them I guess.

I want to encourage you a little more but that amount is too small to make something big from Bitcoin, your hundred dollar can't give you $100 unless Bitcoin double in price and that's $120k we are talking from here which is going to be a very hard journey to be honest but don't give up, you never can't tell, some people that once hold Bitcoin when the price was around $10k were hopeless then yet look at where Bitcoin is trading today, hold and be optimistic too.

There is one advice I will give you, when you have more money later, but more and continue to do dollar cost average, with time you will realize that you have accumulate more Bitcoin, do more of it even when we enter bear market, you will get more Bitcoin by that time and you will make more dollars in the bull run, don't give up.

Welcome my friend and congratulations on you having bitcoin now even though you are just starting out but it's not what the first $100 is good for.
You have to start learning more if you really want to be serious in bitcoin and I think it's never too late as long as you want to be in bitcoin even though currently the price is still quite high but it doesn't matter if the goal is long-term because I am sure that bitcoin will be more developed than today so it's never too late to learn about innovations that can be said to be very good in the last 1 decade.

My advice is that you should try to sort and look for credible information because what is on the Internet is not all reliable so being in this forum can make you quite right because we are in the same destination. Also this is a bit off topic but since you are a newbie if you look at your account now then it would be good to read some forum rules first buddy so as not to break the rules and you know what you have to do

Welcome aboard buddy.

Everyone is late until they realize in the couple of years to come that they're grateful that they've invested earlier than everyone else.

The same sentiments have been dropped for the past several years but I guess that all of them won't say that they're no longer after deciding to invest in BTC.

And after all of those years, it's easy to recognize that whoever enters now is still early if you're for the long game.
