The future of altcoins is great it can used in merchant or services but mostly in gambling i saw many altcoin used in gambling and also altcoins could potencially be high demands same as bitcoin. We hopes that altcoins will rise in the future as bitcoin as well.
Yes, indeed. The altcoin can work together with bitcoin as a payment method, so people don't have to use bitcoin to pay. They could use altcoin for many things as long as the merchant can accept the altcoin. But yes, for now, bitcoin will still be the option for us to make a transaction, but in the future, I guess that the altcoin can be used too. The altcoin itself will rise in the future, and we don't have to worry because if the right time comes to us, it will increase by itself.
Altcoins are being widely paid for in small transactions and if you are in a country that legalizes crypto, this will be easier. I used to use Bitcoin to pay and actually it made me feel very comfortable because no one could know who I was. Also in the near future I think some altcoins will help this life a lot so the future of the crypto market will be very good for everyone.
