Why is it too late ? And you recommend him to buy coins now when this shit is happening with ETC and ETH ? Anyway if you have money invest, but even if ethereum fail (both chains) which is highly unlikely there will always be another coin to mine with gpu, and you can just sell them afterwards...
You noobs are slow but let me try to explain. When ETH goes POS no coin can absorb the hashrate. There will be no other coin to mine for profit. Noobs lose again.
Which will not happen for quite some time, at least not in next 5 months that is current average ROI on ETH.... So please....
And everyone forgets about ETC which will not turn POS and is profitable.... In fact its more profitable to mine than ETH right now... You can argue about how long will coin last but mine > exchange dump everything you mined for that day works quite well....
