How many cryptocurrencies can you buy on OKCoin?

Could you please clarify the number of different cryptocurrencies that are available for purchase on the OKCoin platform? As a user, I'm interested in understanding the range of options available to me for investing in various digital assets. Additionally, I'm curious if there are any plans to expand the list of cryptocurrencies offered in the future, and if so, how frequently can we expect updates to the selection? Thank you for your time and consideration.
