There are two different strategies: buying when everybody is panic selling and buying just in the beginning of great FOMO. Both are working good imho - you just need some experience to catch the right moments in both cases.
I agree, these strategies are working since I already experience to use both. We just need to be determine of what we want to achieve and it takes guts because we dont know what can happen after we buy a specific coin.
Buying during the start of bullish season is fine as long as you're prepared and aware of the risk. Sometimes it doesnt go as planned hence having a plan B is necessary. On the other side buying during dip (or investors are panic selling) is wise as well, but this will depend on the coin. As long as its not a shitcoin and can likely recover then buying at dip is a good choice.
