im already in my 4th year doing bounties and sometimes trading but until now i havent made $50k, maybe you need to invest in a high yield investment program were your investment can be trippled withun a month but its full of risk joining in it so its not recommended.
You can't make $50,000 from bounties unless you do it as your full-time job for the last four years so it's not the only problem with you.You should try trading for that with the decent amount as capital if you are looking to make 50K.
High investment program that gives 300% return in a month will be probably a scam, the best investment I knew related to staking will be gambling sites you can make 7 to 10% in a year.
