a spreadsheet with an addition feature that makes it very easy to track ones investment in crypto, fiat currency, household expenses, important wealth management products

the spreadsheet, could link to price oracles and currency oracle, for up to the market results in value of crypto assets.

the feature to add coins listed on uniswap and other exchanges or creating a custom place holder coin with the ability to get data from a market oracles with the ability track yield on coins in Defi

we live in a time of money printing and possible invisible inflation, by tracking gold and comparing it to our asset value we could see how we are doing in relation to inflation, it would be great if this personal asset spread sheet should pump out this information, using local value markers that could be automatically assigned using market indicators or imputed manually

In today's world there is a big problem of bitcoin storage. ProtonMail has established itself as a reliable service. You are already accepting bitcoins for payment. But that's not enough. Let's make it possible for users to store bitcoins on their wallets. From these purses they will be able to pay for the services of ProtonMail and transfer to other places, at their discretion. It was very comfortable and would add a lot of protonmail stars. You would have had a great commercial success because you are reliable and honest people.
