I don't see the logic in "saving" btc by destroying other coins. Looks pretty scammy to me. Based on the "overwhelming" amount of posts, that forum looks also pretty dead.

Many people have no trust in BTC because so many others manage to steal them. This proves that it is not secure. Perhaps you should wake up to that.
Small coins may be actually safer to bag or spend because for the scammers it maybe not worth the effort.
