I think investing in bitcoin and powerful altcoins is right now and I am investing a lot in them. I am not investing in new altcoins.
Bitcoin is the best investment but you have to read what the topic is all about. OP is looking for altcoins that shares dividends to its holders and bitcoin doesn't have it.
Exchange coin is what you are looking for. Other coins can't give you dividends because they do not have income, while exchanges are earning from trading fees and this profit they can distribute among the coin or token holders. Examples: Kucoin, Bibox or COSS.
Most likely this is what dividend coins are and also those crypto casinos that has their token too that shares dividends to their holders.
