The market is unpredictable so more downfall is possible and I advised you to make your proper analysis before investing of buying at dip.
but Buying at dip is one of the safest and best timing to buy , than in growth because at least for holding there is a big chance of increasing.
I think what he mean is the coins that we pick. It doesn't mean that the coin is cheap now, it's already a good investment. May this bear won't be a way for us to get be fooled by them.
Only the right set of coins has the potential to increase big in the future so they are one's that we must hodl for the long term. We are green now but the increase was so tiny. I don't think someone will be happy with it and I don't consider this as a bull trap either but a bull trap is when there is a fast big recovery, as that's the only way for some investors to be triggered of investing more. That's a risky way to enter but sometimes they can be lucky that a bull run is forming for real.
