Yeah, anyone can start at any time although now is not the best as most people will say the perfect time to invest. A lot of early investors had the perfect price range investing but, if we should give bitcoin another long period of time I’m sure you’ll not meet this price again. At first looking at the early buyers no one thought the growth will be massive as presently a lot of people are forced to invest now because they don’t want to stand a chance missing out the market. What op actually meant seems like an advice but, buying bitcoin directly is more perfect besides invest what you can afford to hold either using any strategy of your choice it’s not a must you go all in at once.
