I think the competition offers at least the same services, with better security. Exceptional rates. Reliable social trading. The crypto broker is well and truly regulated. It has licenses issued by American organizations such as the SEC and FINRA. I regret, however, that it is not regulated by European authorities. So you can see why European investors prefer eToro. I think that Poloniex is distinguished by a plurality of assets, the most essential of which are: significant liquidity, diversification of the crypto portfolio, margin trading, free training… I think that Poloniex's notoriety is low on European soil. Traders still have the 2014 hack down their throats that caused BTC to lose 12.3%. Also, the exchange is not regulated by the European authorities.
