It is a very old technique for this year! From 17K to 5800 USD, Every time people keep saying buy now and hold! But a big number of investors are fed up now, everyone knows when the market goes down, the best time to buy has come! But by seeing such a huge down, investors don't want to invest again!
I don't think so, but for me current price to buy in Bitcoin has very low risk than to buy Bitcoin when it was at 19k$ where risk is already higher and as what we experienced how the market corrected after the huge break out last year. If I have some money to invest I will bought btc at it's current price and keep for long term hold.
