I open a metamask wallet while working on an airdrop and get to work before saving the seed phrase. Before I temporarily copied the seed phrases and moved them to a better place, due to a sudden mistake on my part, those seed phrases were deleted. Luckily I didn't have any dollars in there but I tried to put $100 in that wallet which would have exposed me to a big loss if something had happened. In the end it didn't happen. I would tell others that saving your wallet's seed rate is more important than anything else you do. As soon as you receive the seed phrase, store it in a safe place or you may lose all your money.
