Basically it comes down to most things being listed for sale in Bitcoin prices. If your altcoin drops from 250 Satoshis to 200 Satoshis, it's not really that big of a deal and could recover. When you're looking at it from a fiat perspective though, 250 Satoshis 48 hours ago and 200 Satoshis now is a 50% difference in price.
What I'd suggest is choose a coin that you're trying to accumulate more of (Bitcoin) and just follow the market with the value of that coin. If you're up to 300 Satoshis, you're up. The fiat value really doesn't matter because these are all short term gains and losses. Bitcoin and cryptocurrencies are here to stay so HODL and don't let the big swings bring you down. We've dropped 90% before, then blew past that ATH by 1500%. We'll be fine.
i am a bit confused on the sudden drop in the prices because I am also a beginner and have seen this kind of drop in prices for the first time. FRom what I have seen before, bitcoin's price dropped and then just a matter of 2 weeks, it gained momentum and have recovered and jumped to double the value.
iT made me, doubt for a while if I am going to pull out or hodl bitcoin, i have hodled for 2 weeks thinking that bitcoin will recover, but i lost so much money that is why i pulled out. nonetheless, i will just put in more when value starts to increase again..
