So said bit coin is a bubble just like tulips, some says it is a ponzi scheme and will soon be banned
Other where critical about it's security level and it's vulnerability to hackers well over nine years bitcoin still is the top coin in the cryptocurrency and those critics are still trying to purchase more bitcoin
What is the worst thing you have heard about bitcoin
There are too many to mentioned mate and for me,i do not considered those as worst thing but instead a constructive criticism .because even those are negative issues but still it become publicity and always remember that good or bad publicity is still publicity right?
