If you had done it a week ago then waves would have been a good investment. It has started to rise now, not sure how long it will last or high it will go but the roadmap looks good. Waves overall is a good investment, but bitcoin is very bullish right now so it's a tough call.
Many altcoins value have increased as like waves. Its still the right time to buy waves but not with bitcoin. Buy waves with other currency. As you might be aware that bitcoin is booming up as a rocket. It has reached $17 K plus. What else to say. Hold the BTC you have and gain more profit.
