Pros:
It's fun.
Lots of people enjoy it.
You can make money.
Cons:
Scamming.
New players can join, suppose dicing is fun, dice 1K and leave because that's terrible and they're upset now. This ruins potential donating.
Even if those players stay, they're upset and angry, causing hatred and annoyance between people.
Winners can get really damn annoying ''Haha'' ''Gg'' ''eZ'' ''rekt'' among other things, as well as teasing people and boasting.
Toxicity that happens in general
Arguing over winnings
Ban reports, refund requests, bans, perms, upset people, galore.
Your only real good reason that supports you here is ''I want it. Give it to me.''
that's not really going to fly...
