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.
Depends on the buyer. But I think it's better to wait for the BTC price to drop again. Because logically we trade for profit. When the price of BTC goes down we buy and when the price goes up we sell again. The most important thing in trading we have to be patient and use logic. Don't trade because of emotions.
