Maybe you should buy some more IOTA and lower you onion bags.. I am not sure with onion, but overall your portfolio is great!
I'd have to agree there..
Overall you've got some great stuff there for the long-term.. Bitcoin, Ethereum, NEO & Iota are definitely great holds and I'd be accumulating more of all those wherever possible.
For other strong long-term holdings, perhaps also consider Lisk, Ark, Stratis, EOS, Cardano, Vechain, Nem, 0x, and Raiblocks.
There's still plenty of opportunity to get a good entry point on all of those..
