what do I need to do to make the swap go well for me? Where can I find information about mining?
If you purchased your coins on coinexchange.io -- You can keep them there and in 30 may coinexchange.io will automatically swap them for you. Option 2= you go in discord channel and discuss directly with the developers, they will swap and guide you how to (you will need to have both wallets installed.)
If you purchased them on cryptohub - those do not need to be swapped since those are V2 already.
This coin is not mineable -- here are the options you have to get more EXTN
1. You can STAKE it using your wallet if you keep it open
2. You can stake them on simplepospool --
3. You can join a masternode on simplepospool and get better rewards
4. you can create a masternode yourself - you need 350 coins for this.
The 1.6m Total supply is a very low supply and the circulation now is very low. This coin will raise in value pretty fast if the developers will do their roadmap as debated on discord.
