Timing the market isn't a good strategy for a long term investor because while waiting, he will start slowing down his accumulation pace and since the price of bitcoin varies overtime,the changes in price may even force him to buy Bitcoin at a higher rate especially when he had the opportunity of buying it a lower rate because , while waiting for the perfect timing, the price eventually start pumping. Since the market is very unpredictable,a smart thinking investor wouldn't waste his time timing the market, rather than doing that, he would be more focused on the key thing which is To Buy consistently & Hodl. An investor should be more interested in his accumulating of Bitcoin strategically and consistently using his discretional income and shouldn't stress himself mentally and emotionally with fluctuated movements of the markets.

I don't think they is any strategy that's perfect as they're no perfect strategy use in accumulating Bitcoin. Every strategy has his own flaws regardless on how it works.
