I wish I had put more into NEM (XEM) early on - I always saw it as a "this will blow up, surely... just probably not for awhile" -- well it done blew up. It easily went from a fairly small holding to, yeah my portfolio is almost entirely dominated by it right now.
Tough decisions, keep HODLing or exit, bank some, and rebuy after the sure to come drop.
For reference, the vast majority of my XEM was bought between $0.07 and $0.17, can't remember how much at each purchase. It's ~$1.65 right now - probably getting ready to drop significantly.
Total portfolio, at present value, is approx 1 BTC.
Making up for the stinker that is SALT right now.
And I strongly, strongly contemplated trading that SALT in for VET earlier today - I go back to look and VET blew up again. Ugh lol
I strongly believe in blockchains like NEM and partly don't want to even mess with my holdings in that because down the road I can't imagine it going anywhere but to the moon, it's technical strengths are very impressive and could be a dominant blockchain, frankly, I think more so than ETH. Others, like SALT, Bitcoin Cash (BCC/BCH), XRP, XLM, pure speculation/wave riding, and I say take advantage of that for now because there's going to be wild swings up and down for a good while yet, the bubble in the crypto market itself isn't going to pop just yet. Maybe another year or two or three but individual coins are going to skyrocket and drop like penny stocks, because like penny stocks, market manipulation is insane.
