that's business, my man, so the riscs are -
on taco - it will be discontinued before DMM (that is not a risk per se, that is an obvious statement, but the existing of DMM Eng provides (little) hope, that transfer accs will be)
on dmm - only lang one, truely, with a bit of harder rerolling
edit - DMM (not matter others want to believe) - is first and forevermost, jap platform, so it will never get the popularity of global, ofc. still, the stability is the biggest thing
