Well, first of all congratulations on implementing your store's payment method using Bitcoin
An interesting point is that, as you own a hardware store and this involves knowledge related to technology, as Bitcoin is something technological, there are great chances that your customers will pay using crypto, because some of them know and are already familiar with and use Bitcoin
Although your doubt is already resolved, I would like to share my thoughts in relation to it!
First, I heard that Bitcoin transactions are not the fastest, can I find a way to solve this problem?
So this is something to note, in fact `Bitcoin is not fast compared to some altcoins. But you can solve this by increasing your fee, using a SegWit Bech32 wallet (starting bc1) or even using LN
Is there any way for customers to abuse Bitcoin payments or perform some kind of attack?
Yes, unfortunately yes, and it is double-spending. One way you can be on the safe side is to wait for at least 1 confirmation of the respective payment.
Do I need some kind of machine to accept Bitcoin payments?
No, this is not necessary,
Tell me if there is anything important I need to know before accepting Bitcoin in my store.
• 1° Hmmm, I've been thinking and couldn't find something very relevant.
But I would advise you to research to find out about the tax laws and taxes related to receiving Bitcoin, to see how everything will be taxed.
• 2° - Try to find an interesting video or website that teaches you some kind of step-by-step implementation of crypto like form of payment in a store.
• 3° - Have you thought about using any other crypto for a payment method? ADA? XLM? XRP? (I know Ripple is not the best option lol
), but these examples I mentioned, transactions happen quickly, even faster than Bitcoin
Well, that's it, I hope I helped you
