BC.Game Review

BC.Game is on our list of BTC gambling websites because of how flexible the service of this operator is. It's one of the few offering a sportsbook, online casino, and online lotto on the same platform. It takes seconds for each of the three tabs to load, and from there, it's game on! BC.Game has a lot to offer to casino game fans. It has original games, live dealer tables, and a host of jackpots. A nice touch is that they have a section for high-volatility games.

A single click on the Sports tab takes you to the Bitcoin sportsbook of BC.Game where the most popular markets fill in the welcome screen. The operator gives odds on dozens of sports, eSports, and exotic non-sports markets. In the context of what other bookies offer, the odds are quite good, especially if you follow which fixture benefits from the boosted odds feature. As a whole, this is one of the most widely recognised legit gambling sites on the internet. You can't get it wrong creating an account at BC.Game.

The BC.Game online platform gives you a lot of room to customise your gaming experience, for example, by adding games to favourites, using the provably fair feature, or making the most out of your VIP club membership. There's a blog and forum you can visit to learn more.

Cloudbet Review

With Cloudbet, you get one of the top casinos that accept Litecoin and unique remote gambling offerings for sports betting, live casino, and esports betting. All these services the operator offers under the supervision of the Curacao Gaming Control Board. As is to be expected from someone who plays by the book, the casino stays upfront with its clients at all times and even quotes the theoretical return-to-player percentage of its live dealer games right under the thumbnail of each.

If this is something, wait until you visit the RNG table games of Cloudbet. There are seven baccarat variations, and 31 blackjacks, with the same detail added - the respective RTP below the thumbnail. Some of the highlights in this segment are European Blackjack Gold by Microgaming, BlackJack MH by Play'n GO, and First Person Lightning Baccarat by Evolution. There are so many options that it will take us quite a while to talk them all over. Believe it or not, there are notable jackpot slot games, too, which you can play with crypto thanks to NetEnt, Betsoft, Playson, and others.

Safeguarding your money and processing your payment requests quickly is another thing Cloudbet does very well. On top of that, you can win up to 50 LTC as a welcome bonus. Your Litecoin deposit has to be of value no less than 0.1 to qualify for this promo offer. Things are fairly standard regarding the technical part of sending and receiving Litecoin payments. You have to sign in, go to the designated section, initiate the transaction from there if it's a withdrawal, or copy your casino wallet address and use it to deposit. These are the most notable pros and cons of Cloudbet:

Features

  • Over a decade of trust - Established in 2013 with a strong reputation
  • 40+ cryptocurrencies supported - From Bitcoin to meme coins, your choice
  • Lightning-fast transactions: Deposits and withdrawals are processed in minutes
  • $2,500 Welcome Package for new players within the first 30 days
  • All-cash rewards - Up to 25% rakeback on every bet-win or lose. No rollover requirements
  • Extensive game selection: 3000+ slots and table games, 300+ live-dealer tables
  • No bet limits on some major sports events
  • Private and secure - Blockchain transactions, SSL certificate, multi-sig cold wallet storage
