RE: Coinbase, Gemini, Bittrex, or...?
I will probably need to go back and review my process now after thinking about it. Probably some better ways for me to do things for sure. It seems like you have found a good, safe method with reputable services so you should be good!
Apologies, when I said "Coin option", I was referring to the selection of coins on Bittrex.com. I am not aware of an exchange called Coin Option but it sounds interesting from the name.
Some advice from a fellow beginner, be wary about putting too much of your portfolio into altcoins too early. With events like the forks coming up, things may happen quickly and you could lose a lot of value fast. Holding Btc, Eth, and to an extent Xrp (3 largest by market cap) is just as good or better than holding a basket of coins during uncertainty. You got this though, no worries!
