PANews reported on March 15th, according to Globenewswire, a survey conducted by cryptocurrency asset management company Grayscale and Harris Poll showed that more than a quarter (26%) of wealthy Americans with investable assets of $1 million or more currently hold cryptocurrencies. Nearly two-fifths (38%) expect to include cryptocurrencies in their future investment portfolios. The data indicates that after the approval of spot cryptocurrency ETPs at the beginning of last year, high-net-worth investors are paying more attention to economic conditions and feel more confident about investing in cryptocurrencies.
