Bitcoins price and adoption go hand in hand. without growing adoption, we shouldnt expect sustained price increases. After all, demand (and thus price) is a reflection of real-world usage. But heres the challenge: Bitcoin cant compete with fiat for everyday transactions yet. So how do we bridge that gap?
Who says that BTC should compete with fiat in anything? In some imaginary scenario where a lot of people would start using BTC for daily on-chain transactions, this would, as always, create pressure on the mempool and transactions would become too expensive - but that's why we have LN which enables instant and super cheap transactions.
When we see Bitcoins price surge, it begs the questio... Will it remain just a speculative asset? If so, that makes it a risky long-term hold, especially if adoption stalls. Worse, if whales and corporations dominate supply, they could manipulate the market, turning Bitcoin into a game for the wealthy rather than the many. That would defeat its purpose entirely.
So far, long-term investing in BTC has definitely paid off, for some less, for others more - and no one will say that there is no risk in it, but not only because of volatility, but also because of the security aspect. If you're an investor who keeps your coins on a centralized crypto exchange, or in a hot wallet - or behaves irresponsibly when it comes to online security, then you have much bigger problems than volatility.
As for the manipulation of the wealthy, it seems to me that this game has been going on for years, but there's nothing we can do about it. The only thing we could do was to get ahead of them by buying most of the BTC in the early days and refusing to sell to them today - but the problem is that few people will turn down something like $100k for 1 BTC, right?
So if someone doubts Bitcoins future over these concerns, how do you convince them its here to stay and grow?
Why do you think you, I, or anyone else should convince someone to believe in something or not to believe? If someone is not sure if BTC can survive, grow and whatnot, I suggest you don't play financial advisor in an attempt to convince them of something. I have a very simple answer/message for those people -
wait another 15 years and you will resolve some of your doubts.
