I would say forget mining altogether. Mining itself is expensive time-consuming, and uses a lot of electricity. I would leave that for the pros. The best suggestion is to use your earnings that you get in real life and just buy bitcoin and hold it.
yeah also we can join altcoin investment although it is so risky becouse so many altcoin was dissapear after a few month. but it still good if we know that the developer is have a good credibility. so we can grow up our bitcoin in altcoin investment. i suggest to all bitcoin users to think twice before join minning site.
Yes mining sites are no more legit now so its better to stay away from those sites, and if you are investing in altcoins then make sure that you don't hold them for long term, sell them as soon as price pumps.
It also depends what you follow mines. If you follow cloud mining is a very good thing in the near future and it would be a bad thing in a long time. because cloud mining system uses a ponzi or hyip, so if they will just give you an advantage in a short time after that they will bring a run for all the money invested in
