There are definitely crypto based gambling tokens and blockchains centered around that. BTC owes alot of its success and history to gambling usage and traffic that helped raised its monetary velocity and still does I think. Depends how strictly you mean lottery or just general gambling usage, Im not sure why'd it matter between the two. To some extent involvement in crypto is a gamble anyhow, it can go down or up so not sure I want to raise too much risk on top of that. To build a customer base takes time and trust and its not easy to do, Freebitco has been around years but I'd theres more then one site that'll be relevant.
I spoken to several hardcore players already. So every time they say "there is a lot of other blockchain lotteries".
There is a lot of project that claim blockchain lottery or blockchain gambling, but they are not, in fact, because they merely
accept bets in crypto and this where their "blockchain" ends.
And I've seen good portion of such projects. Very few really do something on blockchain, meaning with smart contract or something similar. It is almost impossible to do Bitcoin-based lottery simply because Bitcoin scripting is very limited and you can't just do anything about it.
Ethereum, on the other hand, is very promising. One can actually program in smart contract accepting bets (ie token transfers), do the round/draw calculations including strong random, and do the payout of prizes.
It would be a pure distributed lottery on a blockchain.
Seen this common blockchain based lottery which had been done on ETH platform and yes smart contracts are indeed great into this field but still it do lacks out interest for people and
rather stick out to those Bitcoin-lottery instead.Dont know on why but people arent really that fan on other platforms.
Counting of the volume on how many people are interested generally with Lotteries then it isnt really that much thats why only a few or close to none doesnt really
plan on launching out their own lottery site due to lack of interest.
