Part of my low cost crypto accumulation strategy is to find free online sources of fiat or crypto. I've previously written about using Coinbase's learn and earn function, which for a small amount of effort awards you with some free crypto.
Well, what I've noticed recently is that new offers keep coming up in their learn and earn function - and what is really good about crypto awarded via Coinbase, is that it is not locked into Coinbase for any period of time. You can do the offer, get the crypto awarded and then immediately transfer it out if you want.

Although completing the original offers in Coinbase a good few months ago now, I've also managed to bag the following ones over the last 10 days or so:
- $4 in USDC for learning about crypto security
- $3 in QNT
- $3 in IoTeX
- $2 in CLV - this was an interesting one, because I'd already completed $3 in learning on CLV and then I noticed there was another two new ones added onto the end for an extra dollar each
So thats an extra $12 for very little work.
This takes my total up to $43 of free crypto with Coinbase alone which I'm quite surprised at. To be fair I do hold some crypto on Coinbase and have used it for depositing cash to buy crypto, so am an active customer, although I am talking about small sums of money. When discussing with a few other people I know who use Coinbase, they are not as active on it as I am, and they dont seem to get the same level of offers - but they do get them. And I've also heard of someone getting an offer very recently that didnt come up on mine.

Anyway, I thought it worth pointing out, as I think its worth keeping an eye on Coinbase and checking their learn and earn offers out every 2-3 days, to see if any new ones come along.
I hope this helps.
