One of the obstacle of bitcoin are the people who are against on it and think it was a scam. This obstacle cause people for not adopting bitcoin despite of the good opportunity that bitcoin can give. When people really understand bitcoin the volume of bitcoin users will increase and maybe it can be the way for them to earn a good profit.
Yes you are totally right about that. The obstacle of bitcoin is not the volatility of it, its normal because its the nature of cryptocurrency. Indeed the obstacle of Bitcoin is the banning and rejecting of it without any reason if its have then its unfair but we can not do anything but to accept and respect it. We must continue to promote Cryptocurrency and lets proved the good usage of it.
they may have thier own valid reasons if they ban or reject bitcoin and yes we cant do anything about it because thats their own country and government . instead of stressing our self too much with them why cant we just foccus on our own business ? we are the ones that can become succesful because we believe on bitcoin and they were the ones that will regret at the end .
In my own opinion the obstacle of Bitcoin that needs to be fix is the transaction speed of the network. But I think it will be covered up by the lightning network which will be done on the next few weeks or months.
i thought that lightning network has already been implemented last year ? but if its not then i think the transactions of bitcoin is already fast compared to previous years and the speed will also improved if you put a higher fees during the transaction .
