I am fairly new to cryptocurrencies and I do not know much about how mining works.
I am wondering since it seems no longer worth mining BTC with a generic computer, are there any Altcoins that possibly have potential that I could mine while at work and while sleeping? Or do I have the wrong idea how it works?
I don't know what I need but my computer I think has a quad-core processor and 4gb RAM.
If anyone can suggest altcoins and how to get started I would appreciate it. =)

Also, I have been reading through these forums and I am wondering, are most of the altcoins being advertised by people that created them themselves for their own benefit? I just can't tell how legit some of these posts in the altcoin section are because everyone is really trying to sell their favored altcoin.
