$1k is sure, we already have ATH of about $700 so why can't it get to the above mentioned price, the migration of many projects from ETH network due to the high gas prices will definitely position BNB in better level in the near future. With what we are seeing it may likely happened before the year runs out so lets watch calmly 
Nothing is sure in this cryto space bud, moreover seing the development of another chain recently like ICX, Solana, and other else would bring Investor from BSC to another chains.
It will reduce the growth of BSC from before, so reaching 1k will be harder than before.
