Bitcoin is special because it has so many features.It is an independent currency which throws a light on it's decentralized nature.It provides it's users a chance to have gainful investments.Bitcoin transactions are cheap and fast.These features and many others make Bitcoin a special currency.
I think, bitcoin has very high selling points and now bitcoin is very much sought after. this makes bitcoin very special in my eyes. bitcoin values can rise and fall so we must be observant in starting investment.
I think, because the selling price of bitcoin is relatively expensive and attractive to a low economy to rise to a very high economy. besides that, bitcoin can also be considered as gold. that can be invested if we need money.
