For me I still prefer bitcoin since it is more profitable but if you want other alternatives, I think next to bitcoin is Etherium or bitcoin cash. They also have future since many investor are also interested on it.
I think the same as you, most people like Bitcoin and ETH because Bitcoin and ETH are the best at the time. There will be nothing that can replace these two coins. From now until the future I will also use Bitcoin and ETH
I know right now nothing is like bitcoin and the ETH but mate I only love the bitcoin, no currency can be like bitcoin ever, price of bitcoin use to change very fast, once it is low then after very short time it will increase once again, my all the time suggested investment is only and only bitcoin, bitcoin has very large scope in market now, and it has very high demand as well. More and more people are attracting toward bitcoin so I would prefer one and only bitcoin, which is the king of all other crypto currency and it will remain number one and my first choice forever.
