With the development of new crypto that continues to emerge maybe this thing will make beginners a little confused, but not for those who already have experience because people like them usually will analyze first, how their innovation /performance/potential especially teams and people the people behind it. If they are better at resolving deficiencies that exist in other cryptos, it's not impossible if their existence will be fought over by the crypto user community, so that their growth can skyrocket rapidly.


At least this's possible will drag bitcoin users whose trust is not yet mature against the popularity of bitcoin, so it's not surprising if in the end they decide to switch to new crypto which they consider better than bitcoin. So, there's no positive effect for bitcoin except the negative impact as I mentioned above.


Every new coin that's newly launched, usually will be equipped with X% profit promos, well in my opinion promos like this will benefit the traders, the rest maybe they have to fight and try to get profits from the newly emerging coins, the same as the previous coins.
