I doubt it can maxe x1000 ! Do you mean it will be at $90 000 at some point?
I've noticed that some people are using x10 as 10 times, others as +10% and x1000 as 1000%. Which one is correct? I understand it is about X times.
Let me clarify 10x means (10-1) x 100% = 900% gain and 1000x means (1000-1) x 99,900%.
My view is that in order to obtain a 100x return you more or less have to invest in something that is a $1M or less market cap now. A coin like NEO or Waves even thought it may be a decent investment, an investor can't really expect it to go up 100x from current market cap levels. At some point it becomes bigger than S&P stocks market caps which is not realistic.
Investable coins in this market cap range may include 808, 1337, Hyperstake, Sumokoin, Linda. The problem with these coins is they are very risky. if the main dev leaves the coins value could collapse catastrophically so its hard to invest big on any of these.
I think a more realistic target is 10x and you might possibly get it with Shift, Xtrabytes, Radium or Crown.
