Let me start with saying I love mining, I used to mine ETH back in 2017 with a 6x gtx 1060 rig... it was fun and profitable.
I was checking your post and I believe it is worth to mention about costs for those that
don't have equipment yet and are thinking about invest some money in buying/building a mining computer or rig. Let me do a small exercise for ETH mining, using the same estimated value of $540 in a year.
| GPU | 1050Ti | 1070Ti |
| Price USD | 160.00 | 380.00 |
| $/year | 162.00 | 390.00 |
| Profit | 2.00 | 10.00 |
In that period, roughly covers the cost of the GPU, so profit should come over the second year; this is without considering the rest of the equipment cost: motherboard, power supply, CPU, etc.
Now, let's also consider, if instead of buying a GPU, one buys ETH directly right now, and again using the same estimated value in a year of $540 and current price of $250.
| Investment USD | 160.00 | 380.00 |
| ETH | 0.64 | 1.53 |
| Future Value USD | 345.60 | 826.2 |
| Profit | 185.60 | 446.20 |
So, just as a complement to your post, so everyone who does not have equipment put in consideration. Those who already have it, while not using it, put some hours a day to mine and get some coins.
That is the advantage of referring solely to mathematics. It is true that to venture into mining seems to have a certain prestige to those who wish to join fully in the crypto-universe, but if we leave aside the romanticism that implies being called "miner" and we focus only on the mundane matter of profitability, nothing seems more profitable in the medium term than buying coins instead of mining them, and this is especially true for those who have great confidence in the future of the market, but also for those who want to avoid excessive expenses and complications.
