+This function calls the [`delegate-stack-stx`](/references/stacking-contract#delegate-stack-stx) method of the Stacking contract to lock up the STX token from the account holder.
 The delegator must call this method multiple times (for all stackers), until enough tokens are locked up to participate in Stacking.
 
--> Reward slots are assigned based on number of STX tokens locked up for a specific Bitcoin reward address

-If users set their own Bitcoin reward address, the delegator has to stack tokens with that address. This would prompt reward payouts directly to the user. However, in this case, a single user will only qualify for a reward slot if the minimum Stacking threshold for the set Bitcoin reward address is reached (~70k STX at the time of writing). If the threshold is not reached, multiple users can set the same Bitcoin reward address to accumulate enough STX tokens to reach the minimum.
