I never look for any investment opportunities that too without any proper recommendation from reputed people. I believe there is no need to look for any other investments similar to bitcoin mining. I believe only with bitcoin investments as it has unlimited opportunities to bring unlimited returns for our investments.
you can still get into mining but not "cloud" mining since they are all scammy sites. you can also start mining altcoins if you are so interested in the mining process. there is only a need for a rather medium investment and then only a cheap electricity. so you can make profit from mining some of the altcoins and sell for profit.
