$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 
I will watch it uncomfortably because until now I'm still holding a few BNBs looking for a hefty profit, so watching calmly without holding several BNBs is wrong, because the opportunities that have been opened up to BNB are amazing, especially when you say that $1K is a very likely thing for some of the reasons you've mentioned, so in general I'm also very optimistic on BNB this year.
