4. I am considering adding a "conservative" multiport that will only switch between NVC, LTC, FTC, MNC and possibly CGB. Would like to hear opinions on this.
This sounds interesting, but what might be interesting is to see some of the other riskier, but more profitable altcoins get added to a superset pool (like NRB, DMD, BTB, STR, ANC, etc). That way you have 3 varieties to choose from.
+1 on the superset pool.
Why not make an option where users can turn coins on/off to their liking and their miners only switch between the coins they like.
