Now that input.io is gone do you have any recommendations for a wallet to use for dust collection?
Some faucets payout to peerbet.org.
If you let your balance build up above non-dust levels ( ~ 0.000055 BTC )
then you should be able to withdraw to any Bitcoin address without worry...
Most faucets these days don't let you withdraw until you build your balance
up to non-dust levels.
If you do use 'any' online wallet to store your faucet BTC remember to withdraw frequently.
It is good advise, imo, to not store any large amounts of BTC online no matter how well
you trust the operator...
And it is a good idea for anyone to learn about security ( good passwords; 2FA[two factor authentication; paper backups; etc. etc. )
no matter where they store their Bitcoin.
