To start,
1. Where do you buy your bitcoin from
2. What exchanges do you use
3. When you buy alt coins and profit, do you convert back to btc? Because what if your profit from alt coins and convert it to bitcoins but bitcoins is low, doesn't that defeat your alt coin profit?
4. Do you convert from bitcoin to usd to withdraw? If so where do you withdraw and which method do you use.
Oh and this sounds like fees over fees.
First you buy bitcoins for fee. Then transfer them to a exchange for a fee. Then trading on that exchange is a fee. Then transferring it another place to withdraw, then the actual withdraw fee.
