In the first week of January 2018 popular exchanges like Binance, Bitfinex, Bittrex have shut down new users registrations to maintain the quality of exchanges. This is when the Gate.io name popped up and after trying for almost 1 month, this exchange seemed to be a solid pick for 2018. The mobile app is fully functional and lets you also add fiat money using AliPay account. You can trade BTC, ETH, USDT, QTUM for any other crypto of your choice.
And remember, you don’t have to buy a whole coin — you can buy fractions of coins. The top coins are expensive, so consider buying fractions of a coin to start if you don’t have a big bankroll. It has historically been a mistake to buy only ETH and LTC because BTC costs more. You should consider which one is most likely to increase in and retain value.
Intuitive UX, focuses on the key features for trading, requires an Poloniex account, no fees. Cryptoriot is definitely my top pick for trading cryptocurrencies with my Poloniex account. You just have to fill in your API key from your Poloniex account and you're good to go. Trade all the Alt-Coins you want to with an visual an intuitive interface. You have an overview of your trades. This app really focuses just on trading without the other stuff with is not helpful (talking about candles). Feedback is taken very serious since this is a pretty new app. Try it out, its worth it!
Congrats @nicolasvh and the team at Opus Labs - this has to be one of the top hunt's of the year IMHO. I'm heavy into crypto HODLing, trading and watching and have tried EVERY crypto tracker available for iOS. It's pretty simple; no trackers come close to Blockfolio, until now. Delta is the first app that has seriously challenged Blockfolio. Even if the team doesn't grow the feature set, it is hands-down better than Blockfolio, both in UI and functionality. Add that to the upcoming features that Nicolas mentions in the last paragraph of his intro and this app is OFF THE CHARTS!
Bitcoin (BTC) is King/Queen; Don’t Get Overly Optimistic About Altcoins. Those who invest in BTC tend to get itchy fingers when BTC stagnates and alts go up. Sure, going into IOTA or ZCash can be a brilliant move at times… at other times you’ll be holding the bag while everyone moves back into BTC. Stick with coins you know and like, but consider always being partly in BTC (not 24/7, but in general). This advise applies somewhat to Ethereum as well, but first and foremost BTC is the center of the crypto economy.
