I have strong hands!!
Hodling
BTC,
ETH,
ICX,
XTZ,
ETN,
ONION,
UTK,
PPP apart from many other minor coins with micro-caps that who knows...

Many have capitulated in the last 300 days, let's see how much it takes for the reversal

I think the fist two will last longer.
Bitcoin and ethereum are good for long term.
No need to ask why for bitcoin and for ethereum, once casper is already implemented people would be hungry to stake their ETH to get passive income. This makes ethereum one of the best coins to hold and having a strong hand, you don't really need to be strong, just simply HODL.
