For a long-term investment, Bitcoin and ETH will be suitable, and other coins should be chosen by everyone for themselves, because everyone sees the prospects of different coins in different ways.
I suggest not focusing on the long term for times like this. the market will experience many updates this year. many projects have announced updates this year. maybe some will succeed, but maybe some will fail. but thinking about long-term investment and leaving this big movement this year will seem unfortunate. stay focused and take advantage of every opportunity available. we can benefit repeatedly.
