What are some good exchanges allowing fixed monthly investment in BItcoin? I need options where my funds will be secure.
You've been here since 2017 (base on the creation of your account), and I believe that in those 6 years, you already know that putting, and storing your Bitcoins on a CEX isn't recommendable because of the hacks that might happen right?
Can I ask OP what's the purpose of asking this type of question? I know that it's tempting to store your Bitcoins in an exchange, and look them grow in amount, but the value of what you can get is way lesser than the amount of money that you might lose if that exchange gets hacked.
Just hold it on a noncustodial wallet like what others shared here already. Good Luck I guess, and I hope you will not get tempted to store it there.
