I started using the DCA strategy a while ago but I do it manually because I prefer to use an electrium wallet and a hard wallet.

What I don't like about the app is its connection to the centralized exchanges (Kraken), I don't know if my assets will be safe on the centralized exchanges, also I can't use the app right now because my country is banned on the Kraken exchange.

I don't know if this is possible but I would prefer if the application is linked with a hard wallet (Trezor - Ledger) instead of centralized exchanges because it is safer.
