Altcoin pump really hard during bullruns. There are much more profitable than bitcoin one can easily make alot and vice-versa .one should also be careful in choosing the best altcoins to invest in and also never invest what you cannot afford to lose cause the crypto-market is very much volatile.
Exaggeration about a certain trend, and when the money flows smoothly into the market, the psychology of the crowd is always easy to fomo to push the price of anything even though you can see really meaningless things but with marketing gimmicks, they still raise prices amazingly.
I think just in terms of cycles that have happened, the pull comes from bitcoin and leads to speculation about the future of quick profits, and then a game of navigation with news good place.
