I'm not entirely clued up on the mechanics of blockchain, decentralised finance or stablecoins...
I only speak from my own experiences. After a long and arduous process I managed to mine a total of 0.97 of a bitcoin (2016-2018) using a combination of Rbox100 100GH/s (my first machine) - this took a great deal of research on how to create a .bat file and use of the pool - eligius (complete noob) and sending my gains to a paper wallet. After slow and steady results I realised my insufficient hash power just was never going to cut it so I upgraded and bought a second hand Ant miner.
This boasted speeds of around 1200GH/s but I was plagued by my inexperience... everyday my machine was reset to the default user and password at first I thought it was something daft like not saving it correctly but after it kept happening I scoured the Internet for a good few days ultimately realising it was due to having certain ports open on my pc allowing an attacker to reset my settings to the defaults.
So I managed to secure my hardware in the end.....
The 0.97 was a combination of the two aforementioned machines, Cloud mining through Genesis (ponzi scam) and daily faucet activities... at the time I'd accumulated this amount it was valued around £6000 per btc.
Unfortunately once I'd worked out how to 'cash out' (another strenuous bout of research) I moved funds from my paper wallet and into a coinbase wallet - over time cashing out X amount here, X amount there until I'd frittered it all away.... big mistake! At today's price it's valued over £12000 double what it was!
One investment I did make was buying £100 of XRP (422 of them) and kept this on coinbase
Wrong time, i missed the XRP bubble... since then a lot has changed, Stablecoins and Defi have entered the game - I converted my XRP (also through coinbase to newcomer DAI coin and was earning results at a meager 2% APY
I thought something iffy was going on with coinbase whenever my 'lifetime rewards' ticker was going down as often as it went up.
Then I discovered Binance and out of a flexible stake of 160 dai I get 0.03858036 or roughly 3p a day!
It equates to about 22 dai a year but as the interest is paid to my spot wallet daily and auto subscribed to binance 'savings' which generates it's own accumulative interest. A sound investment for this noob.
Below is some information on what dai is (taken from another website, crypto news - link provided below)

What Is DAI?
In short, Dai is a decentralized stablecoin created by MakerDAO (MKR). One Dai equals one US dollar (1:1 ratio) and will always remain so until the token is taken out of the circulation.
Dai maintains stable value without centralized trust in a clever and interesting way. It shifts following market changes and thus keeps a steady price against other cryptocurrencies. The process is facilitated by the Maker platform along with the MKR token, CDP smart contracts, and several other stabilization mechanisms. There is no need for a centralized authority that oversees fiat-collateralized stablecoins like Tether (USDT), nor any traditional bank backs it. The project lives entirely on the Ethereum blockchain and its smart contracts, and that makes Dai a truly trustless and decentralized stablecoin which cannot be shut down nor censored.
