Hello, can you please give me advice where i can start trading bitcoin, electrum, litecoin, ethereum and other?

I would like simple good trading platform with indicators, maybe leverage??, then i want minimal fees and spread, i dont want to trade and with my profit only fund exchange account.

I tried markets.com - very good but very bad reviews
bitstamp - fees are very high, even if you buy at 3850 and sell at 3880 you made no profit.

Is it possible to have good platform that dont have problems with payouts and withdrawals and with profitable players for example?
What whould you recommend?

My second question-
Is there any good trusted fund with all cryptocurrency? Something like bit20? What are u using?

THanks a lot! have a nice day
