The majority of this coins have low popularity, thats why they have low fees. If you want to use popular coins i recommend to try EOS or LTC. Store both of them in my ownr wallet
Actually not low popularity, but because the exchange rate is low it seems the cost is low, even though if the exchange rate can be very high then the costs will also be expensive, because the exchange rate is based on the number of the unit price, the same as EOS and LTC, if at all transactions can cost up to 1 unit of EOS or 1 unit of LTC, so that's quite expensive too right?
