Are crypto casinos legal ?
Do they need a license ?
I'm talking about casinos that accept only cryptocurrencies. (No fiat money)
Here some information that maybe help.
If you live in Luxembourg, there are some restrictions:
Luxembourg has an outright ban on slot machines, but gaming machines are permitted at the sole licensed casino and account for a vast majority of its revenues.
A regulation for online gambling is also under discussion, but there is no substantial progress since this issue was mentioned in 2012.
REGULATED CASINO GAMES
Terrestrial:Slot machines and semi automatic games, roulette, blackjack, craps, punto banco, stud poker, trente-et-quarante, Hold’em poker, Ultimate Texas hold’em poker, la Bataille, Texas hold’em poker and Omaha poker 4 high.
Online:Only lottery games are available as nationally regulated products.
There are no legal online gambling offers in Luxembourg (except a limited offer of the Loterie Nationale with a maximum bet threshold per week of €250) 1
There are restrictions to play in online casinos, depends on which country we are talking about.
However, it can be avoided by enabling VPN.
Not sure in China, but US citizens probably can play[2]
