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 do said it time without number, because many people don't get the concept of buying cryptocurrency during the time of investment, in actual sense everyone is expected to buy when the price is at low rate and sell when it increases, but buying a coin during time is accelerated is depends the time frame the coin is going be with you before selling, any investor should have target point to sell. From my views i believe that provided that the investment will take long time before selling it, you don't have to reason the price difference because the more you hold the more the price will appreciate or getting accelerated.
