I'm new to using Electrum I am planning to transfer all my Bitcoins from another wallet that I have to Electrum. I also plan to buy a small amount each month, my question is if I do this and buy Bitcoin each month and generating a new address each time I transfer them to Electrum would that have any negative impact? For example, if I send Bitcoin from Electrum to someone after buying for some months would I have any issues with high fees or something? Also, why are there many addresses created I understand that the change addresses are used when you send Bitcoin but why are there many receiving addresses? Thanks
