Hmmm, can i exchange it asap whitout a crypto-wallet?
right now i use one to convert it from on to a orhter curreny but on that site its require i got a wallet first, :/
So, you basically withdrew your coins from minergate, sent them trough a wallet, transferred them to an exchange, exchanged them, withdrew them to a different wallet...
In this scenario, you have to maintain several wallets, and always pay a lot of transfer fees...
I would propose: withdraw the coins to an exchange, exchange them to BTC, withdraw them to your own wallet. In this case you only have to maintain 1 wallet... Bitcoin even has HD wallets where you don't need to download the whole blockchain.
This way, it'll save you on transfer fees, disk space, and maintenance time.
