Multipools are a temporary fix at best...
It is not a fix. It is a great addition to PoS coins that i believe will be very common in the future.
It adds more liquidity to the coin and open up for further distribution of it.
Is not part of the idea of POS to be energy efficient and reduce / eliminate the need to mine in the traditional sense?
Propping up the value of the coin through mining and dumping other coins seems to be against the whole point to me not to mention potentially damaging other coin prices in the process.
I am a Mintcoin holder, don't get the wrong impression, I just don't see Multipool propping as sustainable.
A coin needs services and vendors who accept the coin to make it a long term prospect and to generate interest and a strong trading price IMHO.
