If you must ask this question, maybe investing in cryptocurrencies isn't for you. Invest in something less volatile which is practically anything else. Altcoins as well as bitcoin will always have it's ups and downs. I see this as buying opportunities and is very normal. Nothing goes straight up but can go straight down.
every moment everything can change for and we cant control it as you are here in this currency all of us may say that this may look worth it why more people are trying to be more practical and also a lot of people may speculate for what will happen next the best thing to have is make some study first cause this is how market works for its movement and nothing may stay in a permanent price.
