Excavating/mining digital coin

Can you please let me know if there is any difference between these two terms- excavating/mining?

both reffer to digital cryptocurrency. thanks.

However, when supply wasn't able to follow the demand everything began to change. price of a single unit of a currency was rising. profitability of mining was also increasing. it resulted in investments in next machines necessary for excavating a greater quantity of a particular cryptocurrency. with the passing of time the extraction of cryptocurrency began to be harder.
