I have test with minimal amount for an early trading bot with Binance. I would recommend using this method to reduce early risk of blowing up your account. Just watch the video.

I got the amounts down to $2.50 USD per live trade including the exchange commission. This is for ETH but I would double the amount for Bitcoin
