For the time being, Ethereum is the best coin to mine, even profitable at electricity of $0.2/kWh. But the price might drop and make it unprofitable.
He seems to don't have any current hardware, and with the end of the mining around this summer (at the same moment as the halving, by the way), I wouldn't recommend him to buy some GPUs just to mine Ethereum, since the hashrate is also increasing.
I couldn't have picked a worse time to enter mining! :/
I only came across bitcoin on a youtube vid last week! I can't believe people have been earning money especially during that peak in 2014!
I mean, I've been looking at other investments too, like airport car parking, that looks cool. There's loads out there.
I've been doing the math with Bitcoin mining, and with the half reward, it doesn't seem to be profitable. Even if I invested 200,000 pounds, it would still take 2 years to break even and by then the hardware would be obsolete. So I wonder how people will even make money from Bitcoin mining after July, unless they upgrade to SP50's, find super cheap electrcity or perhaps less bitcoin will be worth more one day...
