There are some casinos accept altcoins, let me give my favorite casinos list that accepts altcoins:
1. Fortunejack: dash,ppc, clam, xmr, doge, ltc, nmc, nvc, zec, rdd,eth
2. Bitsler: doge, eth, ltc. burst
3. Crypto-games.net: dash, doge, eth, grid, ltc, xmr, ppc, strat
4. Luckygames.io: it accepts 40 cryptos, you can check it on their site
5. Bitdice: doge, ltc. eth
6. bitvest.io: ltc, eth
Actually there are some others, but above sites are my favorite.
Thanks. I will look into them later. But I believe only Luckygames.io would be willing accept Decred in the near term. The rest might start dropping some altcoins like NMC or RDD because they are "outdated".
I second that list.
However it makes you think. Why don't any of these sites ever accept USDT tether?
Basically with BTC at $17000 and $10000 last week, it would make sense to accept USDT so its pegged at least to the dollar.
Because what will happen when BTC starts going back down, and alts are going back up? Also the transaction fees are crazy high at the moment for BTC. Pretty much $20 to send a single 1 input 2 output transaction.
Search about USDT. It is a scam. Bitfinex or whoever is charge over there have the ability to print millions of it to pump into Bitcoin.
