First, don't directly deposit your $50k and hope for a nice return one day. Stay away from margin trading and never use higher leverage more than 10x. 10x leverage should be your last choice if you have an extremely inside feeling and not HYPE after making your triple trading plan. Aim for passive income by investing in stocks and indexes, don't go for the biopharma companies. Just a small suggestion if you look for investing tips: Look for the overvalued shares of airline companies and correlate the charts with previous years and make your decision.
I will advice against using leverage completely unless you have many years of experience and you have proven yourself that you were profitable during those years, leverage is a trap that exchanges use to try to lure investors and traders to take more risk than what their accounts will allow them otherwise, obviously they only present to you the positive side, if you happen to make a good trade then you earn 10x that amount which seems great at first sight.
However you also lose 10x which means a 10% correction is enough to completely get rid of your capital and even smaller movements that can be completely ignored by traditional traders can produce massive losses to your account from which it is almost impossible to recover.
