My favorite is Bitcoin and Ethereum. These two coins are always the king in cryptocurrency, and they are the most worthy of long-term investment. They all give me huge profits, so I always like these two coins.
From the beginning I've only favorite coin it is Bitcoin until now, but when it become more expensive, I find other coin which enough for my money then I found Ethereum. So right now I have two favorite coins they are BTC and ETH because both are worthy, also both are good for holding and investing because they valuable and profitable. And I think this two will become more valuable when years passed by because they both have potential.
in my opinion and favorite coin is bitcoin. we all know that bitcoin are the top cryptocurrency and also bitcoin is a first created cryptocurrency without bitcoin we can no longer know any altcoin now so i think bitcoin is the best coin to choose because bitcoin is profitable and many of us trust bitcoin because on the high value in the market and also the potential of bitcoin that can grow fast your earnings.
