I am currently holding some BTC, ETH and some other coins. I always put faith in the world of cryptanalysts, in which BTC and ETH are the two currencies I really see potential. Market reality shows that its value will increase over time and by the end of 2017 its value will surprise us. Not stopping there, many experts predict it will rise higher by 2018. The BTC market has increased sharply in recent years. It affects other currency markets. And so my belief in their value has increased. Maybe I will sell in the next few months but can sell as soon as the price goes up.
