Cryptology combines both cryptoexchange and brokerage functions. I came there to exchange crypto at first but then decided to try investing in cryptocurrency.
If you're exchanging fiat to crypto, you need to path through the verification proccess, if you're exchanging crypto to crypto, you don't need any verification, that's nice.
If we speak about cryptoexchanging, that's nothing unique. However, in terms of cryptotrading there are some nice features: minimum depo is $10 and leverage is up to 1:100. In terms of trading fees Cryptology is also nice, while other companies charge up to 0.5%, Cryptology charges only 0.2%.
So for me, as for not sophisticated trader, Cryptology seems to be one of the best.
