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.
If you are new investor then my sincere advice is to stay away from current bullish market rather study the market and build your knowledge. It's not recommended to buy a coin when it's at its ATH. This is the time when wise investors sell their coins while people at mistake buy the coins. "
Buy when everyone fears to buy and sell when everyone greedy to buy - Warren buffet"
