The logic for investment is buying low and selling high and currently Bitcoin has a new ATHs is it safe to encourage new investor to buy now seeing how high the price has gone? My fear for new investors is that the don't experience a dip after buying since no one is sure of how far the new highs will reach.
I think this is the right logic and guide for new in terms of investment when the price goes down then the right time has come to buy and Hodl it until the price is up.
you can be waiting for the price to depreciates before you could buy a coin "it's good option in other way round" but think of the process whereby the coin you are waiting to come down a little bit before buying keep on going up or accelerating, i only suggestion goes this way, provided that you are an investor that will keep your coin for long time, you have to purchase any point in time, because irrespective of the amount you purchase right now if it's allow to stay for long time, probably you will make a profit.
