Thanks for all these useful tips @shaidon ! But I am seeing that DECs are losing its value, so at this point of time I am trading off some of my other Tokens (that are not staked) into DEC so that I can upgrade the cards with those and reserve my earned steem aside.
I am actually planning to lease out the higher levelled ones for an affordable price... so that beginners can at least have a feel how they are used. I think especially reward cards because starter packs do not have them.
Thanks so much for stopping by!
