but i think its a good idea to invest in casino because at least we can make steady profit althought we can not expect to get much of profit with the house. but to make invest in casino, we need 0.1 btc and maybe there are any gambling site that will give a chance for us to investing in under of 0.1 btc.
It really depends on how much you can invest and what is you % in the bankroll. With Betking most of us who invested there got very good profits. No investment is 100% safe but I would still consider investing in a btc casino.
You say you earned some good profits on betking, it is either you had some large invest going, or it is either betking's bankroll is pretty small so even if you are not a big investor, you could still end up with some profits.
In my opinion, that's the kind of site you should search for if you are interested to invest in a gambling site, a site that has a small bankroll, so when you make an investment you actually own a decent percent of the site.
if i am not mistaken betking has too many ups and downs and they are usually big swings. for example not so long ago there was a whale who lost a lot of bitcoin in a very short period of 2 days and made all the investors happy but i remember before that investors were losing money most of the time.
Yeah that's a good point I forgot to mention.
Investing in casinos can sometimes lead to a lose, you don't know what is going to happen, and sometime one guy suddenly wins a big jackpot and he takes a part of the money from you, which means you end up the investment in a lose.
