For bitgames and earn.gg no investment needed you just earn points which converts to bitcoin all free methods from offerwalls. Swagbucks is all cash though and giftcards no bitcoin option there.

how many they can give for a day ?
i curious

Swagbucks - Depends more on how much shopping you do and percent cash back each place offers

Earn.gg - watching videos will net you about $3 worth of bitcoin a day doing a few offers will increase this

Bitgames.io - Faucet will earn you about $0.15 a day in bitcoin while doing offers and watching videos seems to land me about 50k to 100k satoshi

thank for explaining me sir.
