What cryptocurrencies does MUFG offer?

As a seasoned financial professional, I'm curious to delve deeper into the cryptocurrency offerings from MUFG. Could you elaborate on the specific digital assets that MUFG currently provides? Are they limited to major cryptocurrencies like Bitcoin and Ethereum, or do they also include emerging altcoins? I'm also interested in understanding if MUFG offers custodial services for these cryptocurrencies and whether they have any plans to expand their offerings in the future. Your insights would greatly assist in my assessment of MUFG's cryptocurrency strategy.
