Good move not posting your volumes as some people do without realizing the risks that brings about.

What are your goals? Everything is based off of goals, not price. I can only speak to the ones I'm familiar with, but here are my thoughts...

BTC: I don't care what price it is. I'm holding long. The trading isn't worth the risk and human error for me personally and I want to defer tax liability.

ETH: I'm biased since I got in early, but $250 doesn't look like a bad price now. It's up to you whether you think the price will fall or rise with proof of stake soon. I think that all the staked coins will create a trend of a supply shortage on the market, and therefore help the price move up. I personally don't want the price to rise too fast here. Slow and steady with healthy moves along the way. Maybe take a little of your initial out as we hopefully approach $500 if you want to lower your exposure or reload if it dips at that psychological mark.

GNT: Not a bad price given that it's been more than double before and they're very young in their roadmap. Getting in in the low .20's was more ideal, but it should hover in the high 20's and low 30's as a potential new base. This is a long term hold for most people, so perhaps set it and forget it for a year - and scoop up more if it falls.

NEO: not a bad price if you just bought it, but it could fall more with a lot of FUD about China's ICO crackdown. This depends on your risk tolerance if it slides more.

OMG: solid entry. You beat me. Maybe trim some of your intial out soon to ride profit and then set it and forget it for a month or two. There will be a lot of developments coming up in the Fall and a tech release in Q4 I believe which should propel this up quite a bit. The advisory board is stacked with huge names, and I'm particularly intrigued with Roger Ver's inclusion (Mr. Bitcoin joining forces with the Ethereum blockchain).

Hope this helps. I do a lot of research and have done well with my strategies, but I'm just an amateur. Definitely make your own decisions and just use our feedback as food for thought. Buy and trade at your own risk, but definitely keep as many coins as you can off exchanges and in secure wallets.
