It's not a bad idea to wait for the price ofBTCto drop before buying.
It's absolutely not right to wait for the Dip before buying bitcoin because you don't actually know when the next Bitcoin dip will occur and while waiting, your accumulation speed will also be affected and you will also missed out a lot of potential profits and markets opportunities as well. It is better you buy Bitcoin immediately your discretional income is ready and with that's way, your focus and accumulation speed/pace will improve and wouldn't be waiting or bothering yourself monitoring/ timing the market anymore.
I guess they still have this trading thoughts and didn't eliminate that thinking about buying at dip then sell at high.
That's why they conclude that its better to do this when they do long term holding. But the fact that market is volatile and we don't know on when those dips they are waiting to come that is complete waste of time.
They are just waiting lots of opportunity to add more volume in their portfolio and doing that would provably not bring them any good result. So better instead of thinking about waiting for the dip they better focus on consistent accumulation then build up their portfolio well.
