Well if you ask me then I would say this.
They are tokens you create on a network.
So for example erc20 tokens on the ethereum network.
Or tokens you create on tron, raven coin, or the Binance platform,
there are numerous.
And I think it is exciting times for crypto.
We saw the rug pull scams of the erc20 swaps platform such as uniswap.
But defi seems to have really taken off.
So hopefully this will allow the defi scams to amplify.
I think the technical term is leverage.
Thus allowing people like myself to make a lot more money.
The fool and their money...
