Regardless of whether it is spot or contracts, the most important thing is to recognize which coins are truly valuable.

BTC can drop 20,000 points in a day, but ultimately it will rise again.

Hype can drop from 45 to 30, but within a month it can reach a new high again.

Worthless coins can surge 1000% overnight, but that price might be the highest point of their lifetime.

Never short valuable coins for the long term, and never hold onto worthless coins for the long term.

Play your cards right, and occasionally make a brilliant move.
