There are many hot topic here these days whether should one invest on mining NOW. of course nobody can forsee the future and everydoy can only make estimations.
Currently the price of GPUs has really increased and no matter what some say it is not possible to find cheap ones, the only question is how expensive they will be. In most cases, under the current conditions, it would take between 6 -10 months to take your money back, depending on if you plan only to add one gpu, create a new rig from the beginning, the price of gpus you will find etc.
My question to everybody is what is the bordeline "take my money back" period that you would accept for putting your money NOW in mining. Is it up to 8 months, 9 , 5 or what ?
I have no idea about the correct action but I would "guesstimate" something like 6 months.
I received 2 notifications of 1080 Ti and 1070 Ti availability from Newegg yesterday $869 and $559 and were able to purchase. I was at work so couldn't use BTC and additional addresses to buy more. It is still possible to get GPUs at decent price, but at a limited quantity. To me if ROI is 12 months, it's still the best investment. If I buy $6000-$7000 worth of Apple stocks (roughly equivalent to a 1080 Ti rig), what will I get in return in 12 months? At best 4%? Whereas, you can sell the GPUs probably at your purchase price or even more at the end of 12 months, or continue mining.
