As of now I don't know any direct way you can buy the coin using Bitcoin, but you can buy it from osmosis (https://app.osmosis.zone) using USDC.
You could just swap the BTC to USDC using one of the trusted instant exchanges like fixedfloat... More can be got here (https://kycnot.me) and then you use the USDC to buy MNTL.

Thank you for your help. But it needs USDC on Axelar blockchain. There is no such thing in the exchanger you mentioned. To transfer USDC to Axelar blockchain you need to use a bridge. And there is quite a big commission. A lot of extra work, as they say
I found a simpler way. I exchanged bitcoin for Atom coin at the exchanger you mentioned. And for this coin I bought MNTL at https://app.osmosis.zone. It seems to me, that it is much easier, and the commissions are small.
