I don't guarantee that Bitcoin is a completely secure asset. But Bitcoin also has many benefits such as:
1. P2P Transfer instant.
2. You can transfer anywhere (same difference in gold, Bitcoin can be transferred everywhere).
3. In addition, transfer costs are very low.
4. Trading profits are enormous.
And many more advantages.
I agree in that BTC cannot be regarded as a safe asset to invest in due to large price volatility which at times of price dumps slumps 'consumer's' confidence.
Indeed, BTC is the most valuable asset to have as a coin but this also attracts a lot of fraudulent activity. So while there are clear advantages to owning BTC (as above) the risk is just as high and because of this BTC isn't a safe-heaven asset.
