Except so far it's only Cryptopias wallets that have had problems, the website just crashed recently when it didn't when Cryptopia was consolidating those thousands of addresses, and I'll wait on the verdict from the mining pools about whether or not a fork has occurred.
Nope - some people on Reddit, Steemit and other sites also have reported recent wallet issues. Just google it.
Time will tell. A lot of people just buy and hold onto their coins but whenever there is panic people withdraw from their wallets and find out it doesn't work.
