I think mostly altcoin which rise has small capitalization that's way they can do 10-40% or maybe it's new coin which come from ICO that's why bitcoin domination stay more o less stable
Now is good time to buy for long term investment all crypto almost -80% corrected from previous high so we near bottom. Buy when everyone afraid and sell when everyone confident in price
I agree it's problem for old hunter with all this shit posters. But I think this will soon change, more and more ICO use platform for bounty instead of forum
Don't need to invest money which you can't afford to lose. Then sky will never fall) Cryptocurrency as other investment can be risky if you don't have special skills
