Start buying altcoins before its too late, the red market you are all complaining about is a big opportunity for those who knows that altcoin time will arrive, all you need to do is ....
1. Buy altcoins that have real use cases or backed with real wprking product, they tend to always have value better than copied projects.
2. Take it or leave it, new good projects will bring better ROI than many old altcoins, feels like we've seem how far old altcoins can go already, now its new altcoins time.
The first advice that you give is correct but it is up to each person to decide if they want to invest when altcoins are still in such a bad shape, but your second advice is terrible, that will only work if the altcoin season began right now, if it was delayed for 6 months then whatever coins that you bought will not go up in value as most likely similar coins will be in the market already, we must remember those coins go up in value just because of the hype and it is difficult to generate it for an old and useless coin.
