$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 
There is no doubt that BNB is a fantastic coin, supported by many exchanges makes BNB worth making as a long-term investment, I make BNB the third largest asset after ethereum and TRON, the price of $ 1k is certainly easy to achieve if market conditions are like today, up only 2 % but the transaction volume is more than $2 billion.
