Cryptocurrency is becoming more popular that even famous people are investing in cryptocurrenc, that is why i think there are a lot of businesses have started to investing in cryptocurrency because they can earn more money here without paying any tax.
How would a person earn more money by just investing into crypto? They need to sell at one time and buy back if they wish.
If the government is not lenient enough they will get taxed on capital gains and there is nothing new in that. Not paying taxes for capital gains is punishable. Even though we think and talk about crypto making our transactions anonymous and untrackable the government are ready to tax us for gains and we have to pay them.
The thing is not same for institutions buying crypto. They literally control the government and they will want to remain rich even after the poor start accumulating bitcoin - by buying more themselves.
