I have always been interested in this issue of security and the management of hot and cold wallets. Personally, I see the use of HWW as an ease of security, which does not mean infallibility. But I have always been very interested in how with a hot wallet like Gorrión on a PC and with the Blue Wallet on the mobile, the first one completely offline and the second one with the public key of the first one in watch-only mode, I generate the transaction in the Gorrión and sign and transmit it with the Blue Wallet. For me, I see it as a viable, safe and inexpensive option. But as I always say, Bitcoin teaches us freedom, responsibility and respect for other people's thoughts.
