Mine il get my bitcoin at trading altcoin that the best trading ever for me. Because if i deposit their and buy some coins il just wait a few days o few weeks the value of altcoin will rise. So i earn always in trading but it is depend on you technics or strategy. And sometime i lose some bitcoin in trading because il buy altcoin at the moment of pumping and il buy altcoin at the price of pump so. It is ready to dump the only thing that i can do is lose some coins. And find another altcoin that has potential. So i find altcoin has dump and potential to rise so my bitcoin get back.
