We both know the purpose of bitcoin creation was to give people financial free and liberation from the government which is the reason why it was decentralized in natiure. But, lately more banks are stepping in into Bitcoin and block chain despite they knew Bitcoin and block chain systems are their competitors.
The question is should we be happy or stay alert because of some foul play?
Well we must be alert because once banks can step up in the world of blockchain and be able to know the weakness of it most probably they can create a plan on how to bring it down.There is also advantage if they would study on how to use the blockchain technology and combined with banks concepts,there adoption happens.
