Are you interested in BTC for the mere fact that the price has been going up since its inception and you think it will enable to make a huge profit or you are interested because you know that the technology behind BTC (blockchain) will change the way the financial world works?
I think this will be profitable, blockchain technology is one of the elements exist bitcoin so much in demand and won the trust of the world community, because the level of security is high. about price rises and price reductions I do not think it's absolute because of blockchain, blockchain plays a role in helping bitcoin stay and move on. and we can not completely rely on it, but have to see and observe the changes that occur in the market, because there are times when people can get stuck because they do not know the time and the right opportunity to choose and make a profit. at least blockchain has contributed a lot to change the way finance work in the world making it more productive, time-saving and easy.
