Save your wallet recovery seed carefully. Don't make a mistake, it could make you regret it in the future.
Regarding the exchange wallet you use, sometimes the exchange changes the receiving address on your exchange account. Before making a deposit, it is better to check first whether the address is still the same or has changed. Sometimes people just copy their wallet from their last transaction. and it could be a delay in funds entering your exchange account.
welcome to the forum. nice to see your enthusiasm. I hope you get what you are looking for in the forum. If you have difficulty, you can ask here.
I've experienced that. My binance account has some years and indeed it changed some adressess. Thank for the hospitality.
If you are talking about the slot to add a Bitcoin wallet address that's available on this forum user profile. It's not a must you add your wallet address and adding an address on your profile does not violate the forum rules but using a self-custodial wallet is always the best for crypto holding.
Firstly, mobile wallet are prone to attack but if you must use a mobile Bitcoin wallet, Electrum wallet is still the best for newbies. For the tax (I believe you mean transaction fee) is base on the congestion level of the BTC network.
Im willing to use a mobile wallet because my computer got hacked once and all my passwords had been exploited. Im afraid it happens again. Thanks for explaining the fee. Thats exactly what i meant.
Yeah, speaking of the type of device with the highest security, airgapped devices should be the safest and they can be used as primary asset storage. Since you prefer mobile, I found open source software that allows your unused android/iphone to become an offline wallet. Read the review here if you're interested

Or if you have a lot of bitcoin (say 1
BTC or more), you should be able to afford a dedicated hardware wallet.
