whenever you come across of holding your bitcoin, it means that you have to hold until the price increases, the scenario is like, when you buy 300k worth of bitcoin in usd and the price of Bitcoin is at 20k and you are expected to hold until the price of Bitcoin increases more than what you purchased it, so that is the essence of holding, in another way round holding of Bitcoin is determined on when you feel to hold Bitcoin, so I believe that every one who hold Bitcoin have a target, so you need to have your own target why holding bitcoin, so that when holding you make a profit during holding of Bitcoin,  but some persons who is new in bitcoins investment doesn't like to exercise such patients of holding bitcoin for long time, some people even get panic when the price of Bitcoin drops more than what they bought bitcoin, I know quite well that bitcoin price when it falls some people regret of why they holding bitcoin that long, that's why I said it's a personal decision of when to sell your bitcoin you're holding or not.

Bitcoin has no stationary value it fluctuates, holding is also a risk one should be careful about because you believe it will rise someday not bad but one needs to study the market very well before making such decision

Yes the DCA method is great, and also what I always say when you think you don't have enough bitcoin and want to buy more but you don't have the funds, get creative! Find new ways to earn bitcoin, sell things for bitcoin, create an ad revenue bitcoin machine on YouTube by making money with the ads, mine it! There are so many ways to accumulate bitcoin

You sound so vague!

Do you have the 15 million ? of course it's better to buy a large about of bitcoin and sell little portions of it as long as the majority of a bigger percentage of the funds is till in bitcoin as bitcoin potential is very high to yield more profits if calculated by the entry price and the expected price within this year one is likely going to hold much or than 6x of its current amount however if you sell a part of your bitcoin then it creates a lower chance of a higher profit the higher you hold and longer the more profit one is likely to achieve from bitcoin.

But then is bitcoin only for investment? no bitcoin has other capabilities which are underrated.

What im saying is this.  If an initial 1k usd investment was made in june of 2011 or january 20, 2012, wouldnt it kind of make more sense if someone chose to wait until they had at least 5 million usd of bitcoin from that initial investment to deduct 300k usd from the 5 million usd rather than just spend it all at once as soon as they reached 300k usd?  Does this make sense?

It means, continue to accumulate more BTC over time rather than selling the little stash you have. Every BTC investors dream is to be able to own enough bitcoins before the market gets to the bull season or to a specific price range. We saw how bitcoin rose from $30k last year and skyrocketed to it's new ath. With the idea of him holding, ot of investors surely made alot of profits from the bull season. Yes that's not the end of it, we are expecting more bulls to come in the nearest future, so the word Hodl remains, keep buying BTC so you don't get left behind.

What we mostly mean when we say you should hold on to Bitcoin is to hold Bitcoin for long period of term instead of selling when you have little profit.

Bitcoin is the most reliable cryptocurrency in the world, it is treated and trusted because it has been in existence for long and people that have their trust in Bitcoin are always winning.

It is a weapon against inflation because if it store of value, it is decentralized cryptocurrency that has given us financial freedom that is why it is always advisable to use Bitcoin as your future savings because you will profit from it and the value will remain the same.

If you can invest it in bitcoin it is fine , but no one can decide for you on how to spend your money. When it comes to investment it is personal and you have to make decision to invest and to spend your money. I will advice you not to invest your money into what you don't understand. If you are planning to invest in bitcoin,  it is best if you first understand what bitcoin is all about . You need to understand bitcoin market us volatile and it is not an investment to get rich quick but a longterm investment.  If you understand bitcoin very well, you will know how to invest your money and you don't need to seek the opinion of others how you can spend your money.

Well it is pretty easy to find price in Jan 20 2012

6.36 a coin so around 160 coins for 1000 bucks.

And Jan  2020 prices ranged from: 7700 to 9500

Thus 160x7700=1,232,000

And 160x9500=1,520,000

Far far far less than your guess of 5 million

Even if you were hold til Jan 20 2025 you are at

160x109200=17,472,000

Which is pretty good.
