Guys the super real problem is how to trasnfer back the stuff, if you don't find a way to transfer back we are fucked up.
I don't know why there are videos saying that the simple thing is when you sell at the expensive exchange in profit, you convert again to BTC ans trasnfer back to the cheaper, and repeat the process all over again.

I did it and it doesnt work
I replied to your email. The next time you attempt to arbitrage, please keep in mind the fact that even if the spread between two altcoins btc/ltc seems insignificant, and appears to be like a sound exit back to the original position/exchange, when you trade it against USD the loss is inevitable!
Despite the total increase in overall amount of coin, its value against USD will not necessarily change.
Don't forget about the trade and transfer fees.
