hey I started yesterday tranding from poloniex and all my capital is gone there because I always lose. the price movement is very fast and I can not always monitor the market (I have a job).
Oh no! You're making a big mistake of wanting to do day trade when you do not have the tools you need. Knife like everyone who does not have time does: Buy bitcoin and keep it in a trustworthy wallet and good reputation for many years. this is the only way you can not lose your money and not have stress every day because the price has dropped. Now on exchange, well and you better use coinbase or even binance and not use poloniex, yobit, cryptopia and hitbtc because these exchange does not have a good quality service, these exchange can create great headaches, so do not use poloniex, Hitbtc and yobit and cryptopia
is there any exchange suggestion that the price movement is not too high like poloniex?
It was not the problem of poloniex, its you problem. but like I said, just use binance or coinbase
