Still the best coin to buy is the bitcoin.  The roadmap of the bitcoin cannot compared by other coins.  It is also the bitcoin who has the highest crypto value. Even if bitcoin value fluctuate sometimes, it surely will recover again.  There are so many testaments how bitcoin change lives of many people. That is the reason why bitcoin community continue to expand and grow.  As the time goes by, many establishments start to recognize it as form of currency.  And I am looking forward that sooner or later, bitcoin will be legalized around the world.
