[artofwar]

Hello there. I have this question to determind which one are more profitable.

If we start at 100k usd in january 2017 to do either one of these:

1. buy GPU mining rig to mine altcoin. change every profit to bitcoin.
2. buy GPU mining rig to mine bitcoin using nicehash.
3. buy antminer to mine bitcoin.
4. buy 100k worth of bitcoin and keep it.

so. which one will be profitable. and why.

If you can, please state your logical calculation. i will update this one the first post.

any other option to put, please advise. should be other than investing ICO or trading.

I would say option 4. Mining is so expensive these days, you need to have really cheap electricity for it to be profitable.
You can also try out Chain Group, but don't spend what you're willing to lose.

Buy the bitcoin. Buying miners are sunk costs and end up being depreciating assets because technology growth makes the machine obsolete over short time. If you want to buy into it you could spread your purchases out over 4 months so you're spreading out your cost basis

so. which one will be profitable. and why.

Use 50% of that money to buy Bitcoin and the remaining 50% to buy a few alternative cryptocurrencies - particularly Ripple and Ethereum.
