Although bitcon price is trading a little high and specially for short term investors, I think that they should wait tell the correction over. Because during correction we can expect that the price of bitcoin will come down a little and therefore we can get an opportunity trade bitcoin in a low price.
Though we can safely say that if we buy now then it would still earn. But i would definitely agree on this one, it is better to wait till the correction is over or let's say when at least the price lower down in this way we could earn a bit more. Basing from the past transactions that I made it doesn't matter what time after months or so you will still earn from it.
