Are there any good ( hopefully trustful ) online alt-coin wallets?

Or, what would you recommend for a solution for storing alt-coins ?

Yes some altcoin devs purchase web wallets and allow their users to store their coins online.

If this is the case its important to make sure the altcoin dev is trustworthy.

Probably the safest way to store any coin is with paper wallets.
