Stop reading those articles where they make price prediction and tries to convince you that the price will skyrocket. See how many past predictions came true. Crazy predictions were made the year before, but we ended up having the opposite. Just do your own research and you decide how much you want to invest and how long you are willing to hold.

The holding strategy isn't bad as long as you are willing to hold your bitcoin until you make profit. Don't use a centralized wallet like Coinbase to hold your coins. Use your own wallet where only you have access to the keys!
