I invested in bitcoin and crypto from the money I got from bounties and airdrops.
I think many people do that too, considering that many people also want to be part of Bitcoin's future. There are still many who believe in the future of Bitcoin, so it can be said that the future of bitcoin might be bright and bitcoin will become a big name in the future. All supporters, holders and the community will certainly hope that way. So there is no other word other than remaining optimistic and waiting for that moment to arrive.
As Satoshi Nakamoto said, in the future Bitcoin will only have two possibilities, namely to become big or disappear. So, I haven't thought about BItcoin disappearing, and I'm sure big investors will also continue to support Bitcoin to avoid that bad thing happening. So the only hope is to make Bitcoin a big name.
It also hasn't crossed my mind that Bitcoin will disappear, because every day Bitcoin is getting more and more famous and many people are investing. I just believe bitcoin will get more expensive in the future. Currently there are no altcoins that are as popular as Bitcoin, so there is no visible replacement for Bitcoin in the future.
As long as there are still those who are looking for and trading it, it is certain that bitcoin will not disappear from circulation and will always be sought after.
That's why, until now, bitcoin has become a very attractive investment, because it contributes to those who hold it. I agree with you that the longer it is, the more expensive the price of bitcoin will be, because the supply is getting smaller, and the demand is quite large.
Altcoins until now still depend on bitcoin. Wherever bitcoin moves, altcoins will follow, and it is difficult for altcoins to be able to compete with bitcoin until now.
