I'll tell you so that the minimum is not less than $ 100 . I know people who $ 100 did for the month of $ 2000 .But this exception, the optimal amount of input 5000-10000 thousand dollars .If you still want to see a profit!
lol . what an analysis you got here . 100 usd turned into 2k usd for just a month ? lol that was freakin impossible mate . you know that trading is not a piece of cake or a child's play , you need to dedicate a lot of time and skill to be able to make a profit but that profit is not really good enough knowing that the crypto market is still collapsing . optimal amount isnt also 5k to 10k usd becase that is already too much and not all peeps can afford that .
for me , id say the minimum amount to begin trading is only dependent on the exchange that you are using becuase every exhcange has a different fee for thier service .
