Cryptocurrencies is getting on fire recently
But i would say the wild raging tons of ICO weekly is bad for the industry.
To be honest, we already have quite enough of cryptos that is use for "General" payment purpose.
Then, years ago we have coins that is made for fun / hobbies like coins with celebrity name, coins with funny names.
Trend has changes, recently we have very great coins that integrate with real use case like
Kickstarter based crypto - Kickcoin
Pension Fund based crypto - Auctus
Blockchainized Stubhub - Guts, Crypto.tickets
And tons and tons of it
I would say there's generally a niche of crypto that "we really need"
It depends on just how successful it could be
