The first time I heard the name of this Exchange, Second BTC, I really thought it was a new cryptocurrency token, like a clone of Bitcoin. However, on the contrary, Second BTC is a cryptocurrency exchange and carries out very secured transactions.
Although I was not able to explore through its platform while I was making my research about it. I wanted to signup for an account with it but I found out that it only supports very few number of cryptocurrencies available for trade. I am a kind of person who loves to trade with many cryptocurrencies so that was what made me not to sign up with Second BTC but you can still make researches on it to enable you decide independently.
