we're on snode and gin platform and the new midas.investments platform also and in discussions with a few more!
Personally, I have been waiting for the Catocoin Portal, on which investors (especially MN investors) can directly exchange their nodes/ coins without corruptions of all their active masternodes.
It means if the Portal successfully imlemented by CatoCoin team, new MN investors can buy their nodes with older MN investors in order to get MNs with old collateral (lower one than current ones at specific point of time).
