For those who have doubts about Bitcoin long term durability, they should look at market sentiment towards Bitcoin to add insight into the Crypto market as a whole. Bitcoin is still at the forefront and will always be the most sought after crypto asset by investors.
For many years Bitcoin has already proved that it is a valuable asset that, unlike any alternative coins or shtcoins could only last for months or years. People around the world already acknowledged Bitcoin's existence but of course, there will be always several people who would not support it because they have their reasons could be financial, too complicated, etc. People who doubted it for sure don't do their own research about Bitcoin, even its history cause we know that statistics don't lie. Even if we look at some charts we would know that Bitcoin would still be alive for the next decade and might reach its ATH peak. This is one of the reasons why Bitcoin is much better in long-term investment especially in the bull run once you accumulate Bitcoin.
