The strength of the community becomes very important, we all know that the bitcoin community is very strong amongst others so bitcoin is at the forefront. but I'm sure someday there will be better cryptocurrency than bitcoin.
Totally it depend on the acceptance of the community, of what they are preferred to invest or used. A lot of altcoins exist nowadays, is just a competition among others the one who have a great value, the one will survive and be on top. But we can't predict which one of them because every time there's always a change in price at the market.
The worth of a coin depends on the community. It totally depends on the users of the coin and its market demand. If people are not interested in the project, the value will definitely drop leading to the failure of the project. Altcoins are new in the crypto world; they really need time to develop themselves in this market.
Yes that is true, and besides it also really matters on how the projet goes, and it also matters on what is going on even if the coin was already in the market, for example updates and good news, that also affects the price of the coin, and most importantly what the coin offers or why do investors have to invest in that product, is it that interesting? Worth it? Or what is its uses and purpose.
