You can do bitcoin on the side, I'm not saying Bitcoin can't be big enough that most of the existing institutions might start using it but you do need a stable income as opposed to trading with fluctuating price.

Why would you trust a newbie with 1 posts with anything that involves installing something?

Which wallet or web wallet service are you using? There may be a problem with the service itself, if its not reflecting, as the the blockchain shows that your tx does have necessary confirmations( min 2-3 for most wallets)

Your TX seems fine at 160+ confs., although the blockchain has been pretty slow these days. I've been waiting for a tx myself to confirm for over 5 hours

I've bet on Horse Racing quite a few times in person, feels really exciting IMO even though there is a chance they may be rigged.

Their offering rate is too high than actual BTC rate ,I would advise to stay away.

No, don't use those sites. I lost 0.01 BTC once and I never went for another one
