PANews reported on March 15 that according to Globenewswire, crypto asset management company Grayscale and Harris Poll released a survey showing that more than a quarter (26%) of high-net-worth Americans with investable assets of $1 million or more currently hold cryptocurrencies, and nearly two-fifths (38%) expect to include cryptocurrencies in their future investment portfolios. The data shows that after the spot cryptocurrency ETP was approved at the beginning of last year, high-net-worth investors paid more attention to the economic situation and were more confident in investing in cryptocurrencies.
