These moments are very sharp and plentiful, but also a lot of coins are scammed and that can ruin the good name of bitcoin, and I think there is an altcoin emerging very good today for bitcoin in the future with crypto exchange.
I think though altcoin looks very nice, but it's still hard to manipulate bitcoin in the market and when investing despite the crypto exchange. we need to eradicate coin other coin manipulations like bitcoin so we as bitcoin users should be more careful so we will not be fooled by other coins.
