With this speed they will support a few hunderd coins at the end of the year.
I don't think so. Everything has a limit, pause and services cooperate with partners they think are the best and crypto services add the coins they think are best for their services. Good crypto, good adoption, strong and healthy blockchain with high hashrates, not much drama.
I don't know any gambling site that supports a few hundred crypto coins.
It is free for gamblers to choose cryptocurrency as an option which is good to use in gambling, I would love to see this because today ETH has been pumping up and it is causing the gas to go high and even I saw $ 15 more that means there are cheaper options in transactions at gambling.
Gamblers want to bet with small and win big. They want to have fast deposits to fuel their games and don't break their mood with long waiting time. I agree that ETH currently is bad for transactions.
I am currently depending on LTC and Doge to minimize fees and am happy to see them add more currencies regularly. Betting speeds is my second favorite aspect of this site.
Litecoin is cool as they give us cheap transaction fees. It has lightning network and the Segwit usage on Litecoin network is very high: 76%.
