If someone give me only two options invest my money in hyip website or put my money in mining, i am sure i am will choose put my money in mining bitcoin. Although mining also have a risk but better i choose it rather than hyip. I think hyip is not good to do. Many peoples was scammed in hyip and loss a lot of money.
Risk exists everywhere, difficulty mining growing. Requires more powerful equipment and more electricity costs and the price of Bitcoin can always go down to the level of unprofitability, it is as lucky.Theoretically you are right but in practice the price of Bitcoin is rising continuously so the mining is always profitable especially if you are operating a big farm. It's only unprofitable for people living in places where electricity prices are high.
Electricity costs is not the only one factor that has to be considered. Serious scale farm requires good facility, maintenance work etc. And after all you could end with pile of electronic useless crap, as bitcoin mining gear can't be use in any other way. However everytime I am impressed how obsolete miners could find any buyer on ebay, but it still happens
