In 20 years, people will either be saying Remember when you could buy bitcoin for only 3500? or Remember when everyone lost their minds and spent millions on useless internet money?
One day cryptos might boom in such a way that basically everyone who didn't invest in them will become poor
We really cannot predict the future. Remember, the decentralized market always has a weakness that is without government control and the market will be difficult to achieve capitalization of hundreds of trillions of dollars. Anyway, let positive thoughts lead you.
The future is unpredictable, so, we all cannot predict into the future of cryptocurrency. What will happen in next minute, we cannot say; talkless of that of 100 and 1000 years to come, which is certainly a long journey into the future. Let us stay positive and we will be reaping the result of our positivity, in cryptocurrency before the 100 and 1000 years comes.
