Yes, it is worth investing now, but personally I believe that we should invest only in top coins, because there is much less risk of losing our money than in little-known coins.
but for coins that are not yet known to be very profitable, you see IQCASH ?, currently the price is All Time High, 10x increase, because this coin is really potential, maybe people do not realize it because in Coinmarketcap IQCASH is in the position of more than 1000.
