Today you can do the same, because if you buy Bitcoin right now at $ 6k you would have much more joy when you spend $ 20ky and keep growing, it is very normal, but it is more satisfying when you know it goes up because you knew it or had it analyzed in that way, because if you study the market, there will always be a phase of accumulation, of upward trend, of distribution and of downward trend again until beginning with the accumulation phase.
This is how I see the market, but when an investor, who has a lot of money and time, buys a lot of bitcoin and expects the bitcoin to rise, when an increase of more than 10% is already being made, it is a lot more profitable than setting up a business and waiting for the annual profit, it is much more juicy than that.
When your investment goes up, it is because the analysis that was done was the correct one and has the reward due to the effort.
If we are buying Bitcoin when the price at below $4k, its gonna be our time to celebrate cause we make gains already(huge profit).
Currently and I know that a lot of people feels bad of not buying BTC during the bear season and maybe they are on the regrets seeing our market rises back. This is how true crypto believer getting even more profitable than of seasonal investors. Better not like with them.
