Hello everybody, 
Please, where do you trade and where can you have the largest leverage?
I use btc.sx (leverage 10 with spread of 3 pts) and markets.com (leverage 20 and spread of 10 pts), but is there something which brings more?
My advice to you is to seek less leverage, not more. As it is now as swing of only 5% would wipe out your entire equity if you were at max leverage, and a swing of only ~2.5% would cause the exchange to force liquidate your position.

I would say that it would actually be uncommon to not have those large of swings over the course of a day, plus the fact that exchanges would easily be able to manipulate the price to force customers on both sides of trading to liquidate positions, effectively stealing their equity
