[2020] Will I lose my 20,000+ Atoms on Bethesda net if I link to Steam?

I've accumulated over 20,000 atoms by doing challenges. I understand that they can't be transferred to Steam, but assumed that if I started playing on Steam, I could always go back and launch on Bethesda net to buy stuff with those atoms. Now I noticed in Bethesda's "Fallout 76 - Special Steam Offers" post that they say "We recommend spending your Atoms prior to switching launchers". So am I going to lose my Atoms if I link to Steam and launch from there, or will I still be able to also launch from Bethesda net and spend my Atoms in the future?
