I've considered creating a family stablecoin first and then an investment coin with liquidity pools.
The stablecoin could serve as an alternative to the USD and be used to settle internal family debts (such as repaying my sister for money borrowed using the family stablecoin instead of the USD).
The "FamilySC" could feature a reserve account with multiple digital wallets that passively generates income through interest, similar to an account here accumulating HP and HBD. It would also hold crypto reserves of other stablecoins (HBD, BUSD, USDT, USDC) and a physical reserve (perhaps under the mattress, LOL). I'm uncertain about the appropriate fees to ensure liquidity; that's something to consider later. A nice additional feature would be providing a Basic Income for family members (I'm still unsure about what would be a decent rate).
For the fun of it, and to provide public access to the token, I might invest several thousand dollars in a liquidity pool to enhance stability for the family project. For instance, investing $5,000 in a FamilySC - HBD liquidity pool.
Next, an investment coin could be created along with another liquidity pool. This time, it would be a FamilySC with a FamilyIC (Family Investment Coin) liquidity pool. The coin would function as a reserve and store of wealth, with a considerably larger pool (worth over $50,000 according to the FamilySC price against HBD, as mentioned earlier).
There are many different approaches to this, but if I were to create my first token, it would be entirely focused on my family and my close network.
I would do something like that using the XDAO.app protocol on something like Polygon. They have some cool features where you could keep it stable but also maybe invest in some stable defi to let it gain some interest. This way the family can also get a governance token. I have looked heavily into this for my clan.
