Just because you suffered a loss doesn't mean that its entirely gambling.
What you need to check is if a certain cryptocurrency or any investment for that matter is adding value. There are numerous barriers, blockages, and bottlenecks in global trade and investments, and blockchain along with cryptos can solve all those problems.
At the moment, the markets are correcting and soon enough they'll start reflecting their actual value, and along with that, there will be more players who could actually disrupt global economics, taking the crypto markets to the stratosphere.
It can be a great wealth builder for those who want it to, or it can just be gambling if you place bets like how you would while gambling.
