Bitcoin and Ethereum is overvalued now and it is very hard to earn big profits on investing in Bitcoin. That is why investing in new and prospective projects is very popular now. Also a lot of attention atracts airdrops which allow to get tokens of new projects for free.
Not all cryptocurrency projects that appear on the market will be popular and in demand which tokens will grow in price. That is why it is necessary to carefully monitor the market to find good projects for participation in their airdrops.
