If I get $ 40 / day choose to invest for Bitcoin, because the current market presents some very favorable conditions possible with investment Bitcoin would be more profitable and not much time to it The second I would also lease mining rig, because it's been my dream
I'll probably do this too. Bitcoins have doubled each year and I think it will happen again this year. It's quite a possible even that the prices could even triple this year as the news about it's adoption is really popping up everywhere. If you invest $40 a day, you get to buy a lot and in the end you'll profit more if the prices really pushes up.
Investing in bitcoin for long term is a good choice but going for buying a mining rig to mine bitcoin is not a good choice as for mining you need lot of mining rig and most important is electricity expenses as most miners are in loss due to electricity expenses. So it is good choice to buy bitcoin and if you know trading then you can do that other then that going for mining is not a good choice at present situation.
