Your price prediction of NEM seem a long way off, may take plenty years before it could happen. Since it previously peaked at around 12000 satoshi in May, therefore 15000~20000 satoshi is more attainable in the coming months.
It seems to me that in the coming months we will see a big drop in cryto - not just NEM. Then again there will be growth, but the next few months are unlikely to be successful.
But this is just my opinion.
