Why buying monero when it is bitcoin you need to purchase Trezor directly from the company, or you can use litecoin as it is only the alternative option for crypto payment to buy Trezor directly from the company.
Bsiq is a decentralized p2p exchange, no need of worrying to buy monero, maybe because you think the transaction can not be tracked, but it is just decentralized p2p exchange (bsiq) you are using and no need to care thinking about buying bitcoin or litecoin for the purchase as well, it can not be traced. Buying the coin you can use directly to buy Trezor wallet will be better.
Why mentioning LocalBitcoins, if p2p centralized exchanges are allowed in your country, then you can make use of a good reputed one, but know that you can not have full control on anything centralized, also that privacy is not possible on such exchanges. But, if possible and that you do not care about privacy (but privacy matters), then you can make use of such service, but it required kyc.
I will buy monero LATER when I get the hardwallet. Trezor only accepts 2 payments on their website, cc or bitcoin, check for yourself.
I am having a little problem with your english, but are you saying I can buy monero with bitcoin directly when I have the trezor model t hardwallet? Somehow I dont think this is true, I thought the hard wallet was to be used just to make sure your funds are more secure and anonymous.
Are there any any decentralized, p2p, exchanges that don't require kyc. I know there are I just can think of any of the top of my head, remember I am new to this.
