We are always encourage to upload and update an ongoing research work on RG including preprint but am worried. I posted an ongoing research work sometimes ago and a colleague told me to remove it if I am yet to publish it. He said if not the next time I log in, I may find the same work hijacked and published by another researcher while I am still searching for equipment to use for my analysis. Is this true? Can't we trust RG for such ongoing project/research work?
