1. Would you cash out everything?
I'd dump the shitcoin immediately for bitcoin.

 2. Would you invest in 5 new icos with each 20 Bitcoins and hold long term (12 - 24 month) and hoping that some of that 5 icos will double your 20 Bitcoins again 10x or more times? = 500 or more Bitcoins

If I thought this investment strategy was feasible, I'd invest some of the 100 BTC from question 1 in a MRI scan to find the extent of my brain damage.
