A minor fall of BTC and stupid money goes panic selling.
Get it into your head:
-unless you have a really really really large investment in BTC, BTC won't bring you as much profit as the best alts that have not already been too pumped up will
-BTC is not end all of all crypto. It is important but crypto does not depend on it
-crypto will not die, it will grow much much much bigger so stop panicing!
-if you chose good alts, you have nothing to panic for! If you don't trust you chose good alts, you shouldn't have invested in the firyt place
-buy BTC with FIAT!
Most people think that the whole cryptocurrency market depends solely on bitcoin. The reason why most people panic, especially does who HODLs Altcoin is that, most altcoin is paired with bitcoin. That is why whenever bitcoin price moves, it affects the whole altcoin market.
