When a price correction or dip occurs, try to buy coins that are in the top 30 on coinmarketcap, they are all big projects and almost all of them have real products, the possibility of recovery will be very large.
Nice suggestion! Buying any of of the top 30 in Coinmarketcap is a good way to guard against ending up putting your hard earned money on shitcoins as the huge investment on any token is usually an indication of what people think about a coin/token, although there're few exceptions, but staying top of the list is a good move.
