Yes I think CLAM will be able to survive 2-4 months. Eventually we'll reach a short term equilibrium. And if people believe in CLAMs and JD long term they'll realize that CLAMs were undervalued during this period and they'll buy in.
Well look as the price drops if people want to play or invest on JD (or if other CLAM services develop) and don't already have CLAMs, then not only will they need to spend less BTC to absorb the dumper's CLAMs, but they will have to buy
more CLAMs to do what they wanted to do in the first place (say invest 10 BTC in JD bankroll). I agree an equilibrium will be reached.
I also think there may be more to the dumping than just the digger. Nearly all alts being in the shitter over the past month for example.
