The only coin Im aware of that has any hope of legitimately obtaining a 1000x jump in dollar value would be Namecoin. NMC is the only well known and massively supported coin with a market cap low enough to possibly achieve a 1000x return. I think if more people were aware of its hashrate and active development as well as a familiarity with the problem that Namecoin solves, its value would explode in response. A lot of folks think it is a dead chain and I think regulators likely have some responsibility for why it isnt listed on more exchanges. Otherwise I believe the price would be much higher.
Currently NMC traded with $4000 volume in a day, which almost considered dead coin. It also has $15million as marketcap, which will bring us 15billion as mcap if price x1000 as you said, which impossible as we know only bluechip can reach that huge marketcap on TOP 10 cmc right now.
And here, just to let you guys know I already made my bet for my next 1000x. I won't tell you exactly what it is to avoid the blame game but will tell you a year or two later. What we'll do is follow the coin's progress. I'll be posting the chart every now and then. I have around 100m coins of this which I spent 200 USD on. Small risk. It's a micro cap coin with a market cap of around 1m when I got in.
If you think you don't want to tell us the name of that coin, wouldn't it better to just close this thread? No point to keep this thread open while you just keep it hidden
