Ledger claims it now stores more than 20% of the world's cryptocurrencies and 30% of the world's NFTs.
Not sure about the statement, how do you come to conclusion like that with hardware wallet?
I think it's because Ledger integrates different coins overtime, and if I had to guess about 20% of all coins (tokens) are on Ethereum, which was obviously integrated a long-time ago. So naturally all ERC20 tokens are integrated. Likewise with NFTS, most are also on Ethereum, so merely the Ethereum integration is what accomplishes this goal. The likes of Solana and other L1 projects increases the % slightly I guess.
