It will be harder, for sure, especially if the price appreciated that much in value. Also, by then, a lot would probably be hoarding bitcoin for themselves in hopes of getting a lot of return in the end. It will be scarcer in the spot market, and I don't think the common people will be able to buy it that easily. In terms of restrictions or regulations, it's a different story, and it's extremely possible that this comes first before bitcoin appreciates in value.
Every Bitcoin will be mined soon and that will be the start of scarcity especially where there’s already a huge adoption in the market, people might not sell Bitcoin that much because of the rising value though some will continue to buy and sell but it will not last. We have a better opportunity now to own more Bitcoin and be ready for the future, better to take that opportunity now and you wont regret it.
Limited supply of Bitcoin and while the demand continues to increase, it is certain that there will be shortages in the future. Moreover, there is
a large adoption in the market, it will continue to make the price of Bitcoin increase, that's why buying Bitcoin later will be more difficult.
Therefore take advantage of the current opportunity where the price of Bitcoin is at a low price, we better focus on collecting as much Bitcoin as
possible starting from now on. Because delaying buying Bitcoin will only make us regret it later, so don't waste the opportunity to buy Bitcoin now.
Moreover, if we study the movement of Bitcoin well, we have obtained evidence that the price of Bitcoin tends to continue to increase. So buying
Bitcoin and holding Bitcoin in the long term will make us rich, so don't ever hesitate to buy Bitcoin.
