It's a tad weird that everytime people try to withdraw around the weekend they receive their withdrawals within an hour after the airdrop has taken place, sometimes even the next block after airdrop.
I'm no fan of cryptopia, but they have grown immensely in such a short period of time. Anytime coin movements peak, delays do as well. With people withdrawing to claim Airdrop, it's likely to cause peaks.
There have been issues with dozens of other coins for over a month. Many of the issues now appear to be resolved. - Actually, truly resolved, not just them saying so.
During the downtime, many holders of various coins claimed Cryptopia is staking the coin, receiving airdrops, etc. However, most of the coin with issues were not POS, masternode, or had airdrops. Cryptopia did put forth extra effort to keep ZCL wallets working during the BTCP fork. They could have benefited immensely by not doing so, then claiming the forked coins for themselves.
