is there any exchange suggestion that the price movement is not too high like poloniex?
There are many exchanges out there. You can check here for a number of them according to their traded volumes within 24 hours: https://coinmarketcap.com/exchanges/volume/24-hour/
However, there are analyses and tactics to master, and then emotions to subdue before you can say you have had some degree of fair knowledge of trading. Go on YouTube/Google to search for trading tactics from notable individuals. Trading without mastering the ropes would always make anyone part with some fortunes. It is not because you traded on poloniex but rather because you are yet to know what to do right.
Plus, trading involves patience.
