Hi guys.
Someone asked me if buying an asic is profitable or not. What's your opinion? Is mining bitcoin or altcoins still profitable for someone to start now? If it is, which asic is better? SHA-256 or scrypt? And which model?
Your best bet is an antminer s3 if you don't pay a lot (higher than 0.12kw) for power. Difficulty continues to go up, so in the next month or so, even the S3 will have a tough time with bitcoin. You could explore the altcoin market, but fairly be warned says I, there be pumps and dumps in the altcoin market. So you either cashout quickly or lose your shirt.
