My opinion about cryptocurrency at the future is good and light, many investor have take investment at bitcoin and keep their bitcoin for long term investment, I sure bitcoin and altcoin have profitable at the future.
Cryptocurrency must be given a long term view because it will take time for the governments to come to full terms with decentralization (something that apparently does not allow them to have full control over the financial transactions of the people). Buy BTC and other valuable altcoins now and keep for a long term because they market has a great future.
