1) Which cryptocurrencies do you trade?
2) Which exchanges do you usually work on?
3) Which strategies do you use in your trades? Does it involve Arbitrage trading? What's the most difficult part of it?
1) Mostly bitcoin and to hedge against bitcoin when bitcoin market is on dump, i hold few high volume altcoins.
2) Poloniex and bitfinex mostly but occasionally also bittrex and yobit.
3) Arbitrage trading can't give you much profit also it will require much more bankroll so i don't try to do arbitrage trading. Mostly i buy from exchange and sell it on local trading platform or directly to local guys at few % above the market rate.
4) Difficult part is to keep getting updated regarding variety of altcoins that you are holding or having close eye to catch some profit on swing.
Important lesson is not to buy when any coin is pumping/bumping and not to sell what you have when it is getting small dump.
