My approach to the altcoin market is different because i think if an altcoin starts pumping then we are already late to invest and investing in an altcoin when it is making corrections can also be risky because some altcoin markets are so manipulative that the team controls the market by dumping their own token so it can go down for a very long time. This has happened to me before so i know the pain. IMO the best time to invest in an altcoin is when it is moving sideways. This is an indication that the early investors are out of the market and there isn't any sell pressure on it. If you are looking for a long term investment plan for that altcoin this is the perfect time for you to accumulate.
