In addition, we have also all ICO's where someone puts 10,000,000 flapdrol-coins on the market and a friend buys one Flapdrol for 10 euros and, hoppa, Flapdrol is worth 100 million on CMC.
And that's the reason who HODL is such bad strategy. If they would be liquid, price would correct quicker and the friend just bought a very expensive Flapdrol.
