I think that early investors were almost purely for the idea. I'm investing in BTC because I'm sure that it will get to the $100K and even higher. I've been buying it at below $20,000 last year and now it's at $40,000+. Not a lot of assets are capable of that.
Definitely Bitcoins are way more valuable than that what it is now. You need to just show trust in the coin and regularly invest in it. Bitcoins have grown massively since its launch and many have witnessed that. You did well mate by buying the coin before 20k usd price. Now the coin will go more up. So if you again buy the coin at this price, then still you can make good amount of profit. Just don’t greed for more and invest in limit.
