Basically all you have to do is send it to Bittrex before the switch, and then they will swap the coins for you. Immediately after you can download the new wallet.
Pretty clean and simple.
OK, what % are you converting to XSI?
I am unsure of if XSI and XSS will be the same as far as price goes etc
Any advice on what % to convert to XSI is recommended and why?
Cheers
