I am not that too good about cryptocurrency but I can say that bitcoin is legit and secured as long as the wallet storing it is safe and legit, bitcoin is easy to be stolen by havkers and scammers but is hard to return but this can be prevented once you are using a safe wallet.
Bitcoin itself is legit, it was made year 2009, how can you say that it is fake if until now it is atill existing, bitcoin lives for 11 years as of now and it will live longer for the future.
I wait for donald Trump or Putin , Simonetta Sommaruga or pope of vatican opinion If btc is good or not!!
If bitcoin Don't get better I give maximum of 1 year more bitcoin to survive!
If things not get better with btc it will not last long
[moderator's note: consecutive posts merged]Bitcoin already survive for more than a decade already and it has been better from where it started I don't know what you are really asking here.
Your question here depends on each point of view it is legit for those who believes it and not for those who have lost a lot and decided to quit on it.
You could never know how much time it has or how long it would last and I don't know how would you say that it would be better because for me it is better compare to it's low value last year.
