It’s difficult to estimate because the advertisers select who they target and it also depends on how many advertisers we have using AdWallet at any time. You may receive 1 or more ads a week. However, there will be days where you might not receive any ads. The number of ads you receive depends on if you are the right match for one of our advertisers. Keep in mind, advertisers choose when to run an ad on AdWallet, how long they’d like to run the ad for, and they select how many of our users they’d like to reach; which all factors into how many ads you will receive.
More importantly, though, the Bitcoin and Ethereum networks are different with respect to their overall aims. While bitcoin was created as an alternative to national currencies and thus aspires to be a medium of exchange and a store of value, Ethereum was intended as a platform to facilitate immutable, programmatic contracts, and applications via its own currency.
There are legitimate concerns about security on Ethereum. With such a complex system, and so many different programs running on it, the attack surface is large. And given the challenges the community faces in migrating to Ethereum 2.0, including a new proof-of-stake consensus mechanism and a sharding solution for scaling transactions, it’s still not assured it will ever be ready for prime time.
You earn free Ethereum by spinning a wheel of fortune wheel. The number of spins that you can have is determined by the “energy” that you have in reserve. Energy regenerates itself slowly, or you can watch videos to top up your energy faster. You need to accumulate 10,000 Gwei before you can withdraw your winnings. But, that doesn’t take as long to do as you have thought.
