1. Altcoins are so many; that they replace one another.
If an old altcoin dies
New altcoins will replace them and old one will be forgotten... It goes on and on
2. Bitcoin has maintained its class and importance;
Is it that bitcoin is the only hope for the future ??
we can confirm that is so. Bitcoin is considered a good value coin and can exist with high value in the long term. but for alts it is always affected by many things and sometimes it will be greatly reduced due to market fluctuations. for bitcoin it is only slightly volatile and more likely to bring regular returns to investors. So we should trust it and hold it from now until the halving event, we will definitely have many rewards.
