I have to say that the “Wheel” game with colors is made in the original way.
I would like to take part in some competitions or contests.
By the way where can I see announcements about them?

Cex is based in London and it is pretty good, but it requires detailed IDs. The same could be said about https://cexbro.com/, but IMO the pain of verification process worth it, as your data and funds will be secure there. In any case, the decision is up to you.

I’m glad that you succeed. And, well, welcome to the crypto trading) From this point, you should think about making more sophisticated trading moves, agree? I guess you will be able to make it right!

Just like Jating said, nothing better can teach than experience - by means of trials and mistakes. To ease the pain, you need to research and self-educate constantly.
Additionally, you need to pick a simple and friendly exchange. In this case, I would recommend you to take a closer look at CEX. The website has not only tutorials for almost every section, but also offers its infobot, https://t.me/CexIoInfoBot, for usage. With its help, you can exchange rates and market movements 24/7 via notifications on Telegram.

I agree with the folks, you'd better start with long-term trading. It would safer for you, less stressful and severe than daily trading.
And I also would recommend you to carefully select the exchange you're to use. As the practice shows, exchanges like CEX (https://cex.io/) or Coinbase are very suitable for beginners like you.

Users’ preferences vary so it would be hard if not impossible to develop a perfect, universal exchange that would fit everyone.

IMO, in order to create a good crypto exchange, you need to combine the best features of the centralized exchange and decentralized one. This means to make a platform as secure as decentralized crypto exchange, and as easy to use as centralized platforms. Plus add to it the needs of high trading volume and liquidity, anonymity, 24-hour customer support, and lower withdrawal fees. If you succeed in creating a user-friendly and highly secure platform, where the users own private keys, you may achieve high volumes. 

Since there is no such perfect exchange yet, I use CEX. Although it’s a centralized crypto exchange, it is a rather secure and reliable platform that has never been hacked. The exchange is extremely easy to use. It allows fiat to crypto trading as well as crypto to crypto - https://cex.io/xlm-usd. The only disadvantage is tedious registration and verification processes due to the KYC policy.

IMO, gambling and gaming industries have made a lot for cryptocurrency adoption as alternative payments. The first boost of usage Bitcoin received after Silk Road site’s launch. Yes, the site was connected with illegal activity, but we can’t deny the fact that due to this site bitcoin saw the rise. The same thing is happening with gambling sites. Playing casino games is considered negative because in some cases it can lead to addiction. Taking into account that gambling goes back thousands of years, it was initially designed for a fun past time. I think the adoption of cryptocurrency by casino sites and games of different types is good for crypto spreading. Unlike bitcoin investors, gamers use crypto no matter what the current price is, but because it’s a more convenient way to pay.
