As the saying goes dont keep your eggs in the same basket. So have you saved all of your btc in mutiple wallets\software?
I like to split with electrum air gapped and bitcoin core.
Should i make it 50:50 even though bitcoin core is always online?
The amount is not that much but i am thinking that if i make it to good amount of mbtc, it will be prudent to divide the amount.
Any OGs who can give feedback?
Is not necessary to save your bitcoin for different wallet, is your choice but it is not matter of insecurity or security purposes. If you want to save all your Bitcoin in one wallet. This wallet is secured and it will be difficult before somebody can remove your bitcoin without knowing your seed phrase. So below is recommendable
(1) trust wallet
(2) electrum wallet.
(3) coinomi.
Depending if not active using trustwallet for an exchange like pancakeswap and mever approved any dusting attack coin I think keep secure when saving bitcoin assets there, bit have good priority for saving assets between exchange market or hard ware wallet. Second option are saving place if OP want keep secure his assest keep safety what ever long or short term holding. But I like saving bitcoin and several altcoin assets on exchange market, easy for selling when price suddenly pump witjout have to move exchange account when trading.
