The problem with investors with small capital is that he has very little free money to invest, and I myself have faced this, when you know where you can invest but no free funds.
The main challenge for low capital investors and traders is that how they are going to make a huge profit out from a small capital? how are they going to do it ? and when will they are going to do it ? that would be the question as we are facing a bearish market, low capital trader won't make any success for the mean time i guess since there are more chances that the peice will decrease rather than rise. Engaging with cryptocurrency will require an amount of money needed to make profit not just with a tenths or even hundreds.
