Perhaps I've always been a lone ranger, which sometimes makes me feel lonely. I'd like to connect with cryptocurrency investors from around the world and share our insights and experiences.
There are only two classifications: either Bitcoin or altcoins, as any coin created after Bitcoin is considered an alternative coin. So, I think your question goes like that. Well, I would choose both. Don't limit your investment to just one, as this market is not for Bitcoin only. The reason why this market has grown is because of plenty of altcoins that were created. While most of them turn out to be abandoned projects or scams, there are altcoins that still exist and are already successful. So, it's just a matter of studying a certain project to see its potential in the future. Also, if you want to minimize the risk in investing, you need to diversify your funds, which means you should invest in altcoins alongside Bitcoin.
Or if you still don't get it, Don't invest or don't put money on something you don't know. Not because you've gone through the website, read their Ann thread, heard about the proect online from a random video on YouTube does mean you've already done your research. Truly do your research by asking yourself is it worth taking the risk and putting off my money out there? All or almost all altcoins does 10x or more easiliy because it has small caps thus very volatile to have price fluctuation.
