I believe there's still time to make serious money with GPU mining.

You just need to have luck to enter early on mining some new groundbreaking coin which will rise in value.

Also, you should never sell all the mined coins, keep at least half, cause value will rise...

i think you should mine another coin like ETH or ZEC are better than bitcoin.

Considering about the performance of this coin they seems to be good option. Altcoin mining at this time if selected the right coin could lead to great returns in future. Just consider people who started mining initially ETH would be a solid started today in terms of returns as the coin has really performed well. The level of difficulty would not that much as compared to btc .
