Perplexed! what im simply doing is to go with electrum only. I'm gonna create a wallet and keep the seed, private key offline or will note it down in my copy. I'm not gonna open a wallet but store a btc like few a month (part of my salary around something 20-80$) regularly. Will see the fruitful result after long years.
Thank your so much sir/mam, further if any problem arises I'll come back to this forum to seek for a help.
https://iancoleman.io/bip39/ is this site safe while creating a wallet and to store my small btc as gives private key for a long term like more than 5-10 years as some YouTubers suggested it too.
