I see your capital OP is very small but what is your goal actually? Making it $10 in a week or in a month?
It is quite interesting to see its progress but honestly OP, having this amount and only trading shitcoins, you just waste your time unless you find it worthless anyway. If I were you, better have the challenge start with $100 and your chances of growing it is huge but if you force yourselves to trade with $3, after a few days now you probably quit.
I think it's just the fact that OP "might" be trying to show the world that you can start with a very very small capital and make some money from it that grows to be something bigger eventually.
Imagine putting 10 dollars into bitcoin per week, there are a lot of people who could do that, it snot "that" expensive, sure in some very very poor nations people may not be able to do it, but it can be done, that's 40 bucks into bitcoin every month, and with some good trading you could make it even as high as 50-60 dollars a month, and that's over 600 dollars a year, and that's a good amount of money, and you keep trading and investing, and in 10 years you will have nearly 10 thousand dollars, that's a giant check for anyone in a poor nation.
With 3 dollars, it's even more extreme than that, I think it would make someone see that it's going to end up with something that will benefit everyone with time, and it should be a great return without a doubt, would help everyone if he can provide proof it can be done.
