Hello all,
To preface, I am a newb
Can someone explain to me how unsafe unconfirmed transactions are please? What is the vulnerability? I have very little experience in this arena, but it seems like some sites (luckybit) can take an unconfirmed transaction and let you bet it on a drop, and other sites require a similarly small transaction to be confirmed.
Why?

If a transaction has enough fee it's expensive to double spend it so I guess it would be relatively safe to take small deposits without confirmations if they meet some requirements
