What do you mean?

Since the very berinning it was known to everybody that only 21M BTC could be mined and miminum unit is 0.00000001 BTC. BTC always had 8 digits after the decimal point. If some gambling exchanges had some artificial minimum limit, that is larger than 0.00000001 BTC, that have nothing to do with bitcoin at all.

Transaction fee could be any you want. Usually larger fee means faster transaction if there is transaction pool queue with more than 1 block to confirm. Fee of 0.00000001 BTC will work perfectly, if you are not in a hurry. Usually, fee is calculated in different wallet programs depending on current blockrate and transaction queue size to be enough to confirm a transaction in 10-15 min.
