We need to find a reason of why the adoption of bitcoin or crypto is less or not as much as it should be. The reason for this is that bitcoin price is not stable and it is too much volatile. When the price is so much volatile, no buyer will be willing to accept it as a payment method, as they never know if its value become less in matter of hours.
It is not easier to convince people to adopt a completely different and new system by leaving off what they have been into for generations. Moreover, bitcoin is highly technical based and people need at least an internet connection to kick start with bitcoin ecosystem. I believe these are two prime reasons why bitcoin adoption is not at a pace like we are all expecting. I too agree that lack of adoption by new people must be a main problem with crypto market by this time.
Due to lack of adoption by new people, I believe bitcoin is fluctuating weirdly and I just see that many people are considering volatility of crypto markets as their main problem right now. I believe when we are having more new people start adopting bitcoins, this fluctuation problem will be eliminated.
I don't that its really that much tough because people are educated and there are allot of systems which are able to satisfy those who are uncertain about investing money into crypto. According to me the actual problem are those who once buy and then sell for panic which causes price fall. This way I advise everyone to hold their coin and never make the market fall.
