That level of burn would be ABSOLUTELY AMAZING!
You could argue that in about 12-18 months the ENTIRE SUPPLY could be held without a burn & 3-6M holders averaging as little as $3-$5k per holder.
With 3.9% of the global population currently in Crypto, there is PLENTY ROOM for more upside in growth, adoption, users, holders & the like.
So if we're ALREADY approaching 3M holders (despite etherscan showing 1.08M, we know that many of the top wallets are brokerages & exchanges like; Gate.io, OKEx, Binance, Crypto.com, KuCoin, etc., & so do not account for ONLY one holder), then how long before the number of holders organically doubles to 6M.
BUT with a huge burn the kind of which you are describing then 3M users holding the same average $3-$5k means MUCH HIGHER prices as the supply would leave ~89T SHIB/6M = 14.8M tokens which at $.000035 = $520/holder. But if we look at SHIB becoming a "Top 3 Crypto" as The Lead Developer of SHIB Shytoshi has proclaimed, then that means a valuation likely near $1Trillion. So 89T SHIB with that $1T Market Cap puts the price at around $.011236
$.011236 is 321x money (from $.000035)
Obviously that does NOT INCLUDE more than the 3.9% (of the current population holding Crypto), & does NOT account for the value of IP, Gaming-revenues, NFT's, NFT-Gaming, ShibaNet, ShibaSwap 2.0, Shibarium utility, other businesses, adoption, utility use-cases, additional demand & the potential for a GROWING MARKET CAP as time goes on.
