The no use of word, "May" has changed the whole meaning.Yes, but you had mentioned this previous le 👇 that's why I asked.
Read it as: Also if someone do less than Rs.1000, they may lose their welcome RPs.
As TnC says first txns then we mostly take it as first txn using card. If they had categorically written that you will get it once you do Rs.1000 txn even when your other txns are less than that, you will get this 2000 pts. But then they have also mentioned that after July 2023 which means when IDFC started whole reward system, it made this welcome benefit for all card holders i.e old acc. holder too.
As @Abhishek012 told other people have got it so it clarifies that once you do Rs.1000 n above, you will get 2000 pts no matter what.
All in all to get it you need to do 1000 txn. If someone has got welcome bonus of 2000/4000/8000/20000 below that then this TnC has no meaning at all.
