Gambling always make you loss even if you've change your winning chance into 90% doesn't guarantee to make 18 green in a row.
Maybe you can try different method for example, I'm using high risk high reward gamble, 1000 sat / bet with 0.01% winning chance.
Once you hit it , you made a huge PROFIT !

Kinda difficult to understand what you're asking since your English is not the best.

You're looking to buy Bitcoin with USD (with CC?) without having to go through a verification process?
Try finding a seller on Localbitcoins or Paxful, one that has good reviews.

If you are looking for web wallets ,i think xapo and coinbase allow you to sell your coins,it all depends upon which country you are located,as i think there are restrictions in some countries,if you are looking for exchanges then you should verify your ID .

In my opinion its better to buy altcoins such as ethereum, monero dash, litecoin ,etc. I think these coin have good potential to grow in future.
You can buy different coins. Dont invest all your money in a coin like bitcoin or any other. Its so risky.
