I have invested in three coins on bittrex and it has remained at the exact same decimal number for two weeks and hasn’t done anything. I can take a screen shot to show you if you would like. I have roughly $250 of my own money invested and I haven’t seen any growth. It’s really upsetting.
I can't say bittrex is scam as i never faced any suspecious activities with my account there but when you talk about decimals, i realized you have less knowledge about trading and that's why you are watching on decimals of you available coin. I would like to give you an example that if you bought 0.01 BTC and it was equivalent to $152 at the time you bought it, now you can't expect to grow from 0.01 BTC to 0.02 or more, actually the decimals will remain same as it was on the time you bought even after years but only value will change. For example, 0.01 BTC was $152, the same may be greater or lower than $152 from time to time according to market
