I recently joined a new site since last week, called Bitvest. I put in my investment there, more than $150. It is a big amount for me,,, but I had been collecting some bonuses recently from the end of 2018 and decided I will invest the extra in BTC. But different from my own personal holdings, I wanted to experiment by investing in a casino bankroll.
Many others as mentioned above, but I wanted a site with visibility:)
Im beginner.How much should I start? Im afraid that is scammers.
You can start for $50 to test, and then you can see how much you will get from the investment. And if everything run well, you can invest more like $100 or so and see how much profit you can get. But remember you don't have to use big money if you are not sure and you are afraid of scammers. Just use the money you can afford, and you will be fine to invest in the gambling websites and don't greedy to chase bigger winning of money.
