This is a great idea. But I miss this opportunity. So now I am wondering where Bitcoin will go in the future. Correcting all the previous mistakes and now I have a plan for Bitcoin. Now every month I buy a few dollars worth of bitcoin. Now if I buy $ 100 worth of Bitcoin a month, how many dollars will I have after five years? Now that's how I think. Hopefully, I will get good results this time by learning from past mistakes.
It should be less than if you invested 100$ 5 years ago. 5 years ago bitcoin was like 500ish $, so of course what OP posted looks amazing, but past performance is certainly not indicative of the future. In fact, if you have paid attention, bitcoin increase in value is slowing down overtime. Yes it still goes up, but less and less.
You might be lucky and catch a bull run, but don't count on it as long term. If a bull comes it will later correct back where it should be.
Zoom out completely and look at the curve of bitcoin's price history, it is a logarithmic curve that starts nearly vertical and ends nearly horizontal. Look in history you will find this curve in things like gold...
The most earns went the the bravest early investors. You can no longer live off bitcoin as some people did back then, but you can still use it as a means of preserving value, a way to keep your savings off the hands of banks and governments; more importantly, they cannot destroy its purchasing power no matter what happens, unlike fiat.
Diversifying is good, keep spreading your investment across various things if you want peace of mind.
