Do you think it's worth selling some ETH to get some POSW now? I've had a good look at it a while ago, and it seems promising even without whales. But then again ether... 
If the coin you are holding is in profit you can keep a percentage and book profit in rest of the coins and enter promising coins but i am not certain whether POSW could get pumped to $5 ,i will wait and watch the coin and if there is a big buy order then i will make a decision about entering the coin.
