Ive owned btc since 2014 and a bit of ethereum
Now I've spent it all.. and was wondering If there are any offers like the clam offer to get some free crypto for holding wallets since way back.
Anyone know of any places to get 10-50$ free btc?
Yes there are many website who pay per hour free crypto claims. Like clsim btc btc hourly etc you can claim satoshi by those website
These are called faucets and it would take a pretty long time to get 10-50$ off them. They weren't profitable back in 2013-2015 either, as even then they gave a pretty small amount of BTC per hr/day.
There is no way you can earn BTC or alts without effort unless you buy hardware & go for mining. One of the "free" (but you have to spend time to do this) ways to earn BTC is spending your time here earning activity and joining a signature campaign to get paid for your posts. Nobody will give you free money.
