Yep - we don't need to mourn it or the opportunity of it - after all, BTC is available all the time.
Not as cheap as it was before. Everyone could have bought Bitcoin when it was below $100 dollars. But most of them did not know about Bitcoin. Let's say a lot of them knew, but they did not take want to the risk of having internet money. People who decided to take a risk and try Bitcoin back then, some of them are millionaires. Probably some of them are billionaires at this moment. Who knows?
BTC will be available in the future as well. But we don't know how much it will be worth. But I am giving you a guarantee that it will be more expensive in the future.
And being expensive means that we will all have to fight it out because it's going to be highly demand because every 4 years, the supply is going to be scarce because of the halving. So now, we have to fight it out not just with institutions but with government as well when some of them are looking at it as Bitcoin reserved.
But still though, we still have some time, it doesn't mean that we need to get 1
BTC right away, because admit it or not. Majority of us here doesn't have that money because we are just average joe retail investors. But we can work it out like buying in small units and then HODL on it and save for the future.
