The rapid growth of coins does not always indicate its success as the price may also fall rapidly. Therefore, it is better to let bitcoin grow slowly with falls and growth, but confidently.
volume is the best answer, many altcoins find high performance but soon gradually weaken in less than a week, in the end they will face the fact that investors only take advantage of their coin trading and finally return to buy bitcoin. There must be a long experience to at least enter the top 50 coin markets.
