A senior executive of Spanish financial giant Banco Bilbao Vizcaya Argentaria (BBVA) said on Tuesday that the bank recommends wealthy clients invest up to 7% of their investment portfolios in cryptocurrencies. This is another sign that some banks are gradually accepting this field that has long been avoided by mainstream finance due to risk issues. Philippe Meyer, Head of Digital and Blockchain Solutions at BBVA Switzerland, stated at the DigiAssets conference in London that BBVA Private Banking recommends that clients invest 3% to 7% of their investment portfolio in cryptocurrencies based on their risk preferences.
