There are so many suggestions people have given you till now but I will suggest you to try with Stellar(XLM). You will surely fall in love with this coin. There is no delay on network and the Transaction will happen instantly. Try this and don't forget to give feedback 
Ripple also has very fast transaxes like Stellar
however, both of these coins are owned and fully managed by large banks
it is not safe to keep these coins for a long time, because their price can fall at any moment.
I like Bitcoin the most for the purpose of buying coffee
for a long time, like many crypto enthusiasts
I have dreamed that I could buy coffee for this coin in a coffee shop near my home
