Bitcoin is worth buying all the time
People should buy Bitcoin only if they are ready for a long term holding. If they are weak for panic or lightheaded, they will sell as soon as their investment looses 20-30% of value. Or, if they know how to trade and earn on falling market.
I doubt that those who has bought bitcoin when its price was +60k, buy more now. They have probably get disappointed in crypto and sold, or cry right now. As this topic was created during major drop - I would definitely suggest to buy. But buying every time at every price I think is wrong.
