Bitcoins!
For two reasons : 1.Safest and direct transfers and withdrawal policies
2.Most of the websites almost all my fav's accept bitcoins as the primary source of payment .I don't mind betting in alt but have heard people getting scammed while the transfers were issued for the first time to random accounts .
Yes but lately with the attacks on the network sometimes it takes forever for a transaction to appear on the blockchain. Also the difficulty is weird and sometimes it takes 30 minutes for one confirmation.
I noticed this too. Usually my deposits are instant but lately they have been taking 15 minutes and these are just deposits. I can't imagine how long it would take during these attacks to do a withdrawal.
