this show that on 7 May, the majority (nearly 95%) of bitcoin addresses are worthless, more or less. Only around 1.5% of addresses hold any significant value (>1BTC)
But what it doesn't tell us is anything about wallets. If I've been paid 0.1 btc to 20 different addresses, my wallet has 2 btc but shows up as 20 "worthless" addresses in that useless table.
