If realsolid had been a scammer, he'd cashed out within the first 3 weeks. When 1 SC was 0.03BTC, and there was a market volume > 200k on bitparking. Instead he sat down, reacted to threats, changed a lot in the networking of solidcoin, and released SC v2(and soon v3). Sorry, but putting much hard work into a scam after you missed the opportunity to cash out big just doesnt sound practical for a scammer.
I of course know nothing about whether he is a scammer or not, but if CH was one he maybe thought that SC would be worth more than .03 btc, and decided to wait. And not he would be putting a lot of work into it so that people may get confidence in it again.
But who knows! God know I don't
. Really couldn't care less about SC and the drama around it.
