I have used Binance with no issues so far. Down the road who knows though..I have a bunch of free Ripple. I was starting to hear some buzz about it a month or so ago. Ended up getting a bunch at $.40. Took profit to get my initial investment back and now riding some free coins.
I have been making good BTC trading: ADA, XRP, XVG, BTC, ETH, and NEO.
I'm trying to accumulate as many of the top coins I can (after getting all initial back) and plan on holding on for the long term.
I've been trading as a hobby for the last 15 years or so. Nothing too serious, but enough to pay for trips and buy some extra toys.
I have made more in 3/4 months than I have in all my years trading. If you can read charts and have a solid process it is pretty hard NOT to make money.
Not sure how much longer this is going to go on a la beanie babies, but I hope to make as much money to payoff bills and set us up for the rest of our lives.
It's crazy.
GDAX:
If you have a Coinbase account you already can sign into GDAX. It's the same account. Just login.
You can ACH transfer money from a bank account. It takes a while though. Or you can buy with CC on Coinbase and then WITHDRAW/Transfer from GDAX. It's free. If you send BTC you pay network fees.
Protip - don't send your money as BTC to exchanges. I convert to ETH/LTC. Faster and cheaper fees. Then convert back to BTC on the exchange.
NEM did great this week. Ripple great these last two months
