I think you can buy now, because now the price is also still cheap, so it will also generate many profits by selling higher prices.
I feel that investors will be worried seeing market are in dip for many days and even not thinking of buying more coins right now. May I say that they aren't wrong, of course we also need securities of not losing. And even the price is high still we can earned profit from them and much comfortable as market grows day by day rather than in dip situation.
