I want to make an investment with just $50 as a beginner i don't know which coin am i to start with but i heard been hearing a lot of people both physically and on social networks saying incredible things about (BTC), that is the best. please i need your assistance.
The best thing to do with that amount is to buy data and keep learning online about Bitcoin and cryptocurrency and how best to invest in them and what the waiting period is for that investment to mature, most times some of those with little amount in capital see Bitcoin as too expensive for them so at the seek to buy other coins who promised high return but with higher risk of losing all your money if the coun gets dumped and become worthless.
So the best choice of investment should be bitcoin but with that amount you mentioned in the ops, it seems that you may hardly have a significant place with Bitcoin and how long you may have to wait to see your investment yielding profits.
