Look at what happening around. The first cryptocurrency bitcoin was invented to reduce the hassle of third party and have borderless transaction. Isn't it true? Now, look at what happening. People are more into investing it than using it as currency.
Most interesting is people are most interested in coin which give more ROI, they are not interested in the currency-ish of a currency.
For example, some people are talking a lot about BSV, but if they have some research, they will never take it as currency, but as this is giving a good return now, it's best for them. Why man? Why don't we look into a decentralized coin? Why do we only take it as investment? Did Satoshi ever take it as investment? Or he invented Bitcoin for borderless payment and solution to the intermediaries problem?
This is a very good question.
The fact is that bitcoin is not regulated by states and state organizations like SEC, so whales use bitcoin and cryptocurrency for the pump & dump scheme, simultaneously attracting new capital of trustful investors, buying up bitcoin for 3 thousand and selling for 10-20 thousand. Without government regulation, we will have very high volatility, and in this case only crypto enthusiasts and risky guys will accept bitcoin as payment. Remember the dollar that we are happy to accept in payment in any country. I believe that bitcoin should grow the ecosystem and reduce the turnover of each coin per year by a factor of ten (both on the blockchain and in trading), so that people can stop seeing only the opportunity to make a profit in it. Otherwise, in 50 years we will see a great price, but the exact same volatility and desire to speculate with crypto traders.
