For me it is never too late to buy bitcoin, depending on the vision and mission we want, for short trade or long term. In the short term it is never too late because we can make profits from the altcoins we buy quickly. for example, in the last two days I have gotten quite a lot of profit from DOGE and TFUEL, ZIL, because their pump is quite fast, until now Doge is still a pump and I can take advantage of the difference.
But for long-term investment, it is still possible because BTC is still at 34K with predictions this year will be more than 50K. In essence, it's better to buy than sorry to see crypto price increases without us owning the assets.
