Hello,
I have been sniffing around the crypto market and I have decided to perform my first investments.
Since I am starting from zero, I would like to use my credit card or my bank account to deposit USD or other fiat currency and use some exchange to buy BTC, ETH and so on, trying to build up my portfolio.

For convenience, I would like to use one service for everything: it seems Spectrocoin would allow me to do deposit, exchange and wallet in the same platform.

Is that a good service? Any other comparable option?

Thanks
