But the best thing is where to keep it until I get a distribution of 147 billion tokens

Why do holders of $Jager not receive distributions from Binance Alpha?
Simply put, all Alpha users participate in a single wallet on Binance, and the Jagger site cannot distribute them. The site sends the distributions to Binance, and Binance redistributes them according to a predetermined schedule, either monthly or weekly. Anyone who owns $Jager on Alpha at the time the data is raised receives the distribution. If they sell before the data is raised and then repurchase after it is raised, they will not receive the distribution.
