Crypto adoption is have been slow in recent years and many shops are still not aware that there some kind of virtual currency in the online world that can be use in any kind of transactions. This year might be different because the market is bullish due to continues climb of bitcoin and some altcoins. During this uptrend of bitcoin, many merchants and investors might get interested in the cryptocurrencies and the bussiness people might try to use bitcoin as a payment in buying their goods.
Exactly, today there are still few shops that are using crypto out there. And these are IT shops for the most part. Speaking about bitcoins, I think it's risky to use them as a payment method.
It is fine to buy it quickly and now as it's not risky now. Even the crypto rate doesn't change that fast.
