GSM has 5-6 stable connections 3 of them are Full hosted nodes, so it's safe to install the GSM client, and save coins there if you don't trust Yobit.
However i will start to look for alternative.
GSMcoin was never been an ICO. Just POW/POS, but POW is over long time ago.
I ordered another block explorer, i will publish later, when is ready, just to have 2 block explorers, it's always good to have a spare one wheter is that exlporer or exchange.
