bitcoin is still a lot of useful on the internet.and bitcoin right know cannot be said as success innovation" but blockchain and the concept of bitcoin it self it was something will really need in the future . bitcoin will be bigger than this. price is no longer a reason to say a project failed or not.
It is very much useful and it will grow over the years and if some more countries official make it legal then price will shoot like anything. So ideally on every dip it is the best opportunity for people to keep investing and saving for the ahead.
I really do not care what useful that bitcoin brings because in my opinion, bitcoin is just a tool for investing, people just pumping and dump its price continuously to make a profit, and when this becomes too familiar and unusable, it will definitely disappear when it no longer makes a profit. You and me or many others are just interested in profits and profits, bitcoin will soon die someday but the distance to that stage is still a long way, it can still maintain some last strength
