Lots of paranoia plus crossing of t's and dotting of i's.
What is your paranoia ?
People gave you some advice and below is a guide from LoyceV, that you should read
Transaction fee
- There are weekend and hourly effects so please make sure to have plans for your transactions
- Check details with Guide to check fees: Taker, maker, deposit, withdrawal, transaction fees (Read the bottom part and hyperlinks). Weekends have effects on transaction fees with both Bitcoin and Ethereum. Sundays have lowest transaction fee and lower than Saturday, in average/ median. Hours from 0 to 12 UTC usually the best time to get cheaper transaction fees.
