We all know that some people use btc for negative purposes (drug dealing, terrorism), so is bitcoin being a decentralized currency is really convinient? Why?
Where do you live man, on the earth? Then know this, there is neighbour next door who is druggist and keep taking drugs all time. Do you know from where he buys that? Black market on the beach side and that too with his dollar bill. Dam, dollar is centralised currency but is it convenient?
Obviously it is convenient because its being used since long time and people use it anyway. What is wrong with bitcoin then? Just because it is decentralised doesn't mean anything about it. It's convenient and it gonna be there forever.
