can you buy ADA on Poloniex for $3? I don't use Poloniex but some exchanges have minimum transaction order limits. but if you can do it, good luck with your trading again. we all would be quite happy to see you update everything in this thread of yours.
but with capital of $3-$10, I will usually go to trade memecoin. it's just a fad just to test your luck.
Once again I wish you luck.
