I think you just should buy some good investments that have some great fundamental. Dont look at the price all the time. Imho the most old alts are correcting, while a massive new wave of new alts is going to boom with bitcoin.
But i think thats not the end of old alts, theyre just loading fuel for the next leg up. We just need bitcoin to cooldown a bit.
If you want you can just look which altcoins are down since few weeks, but which have big capital behind, market volume like 100 Million and more. I dont look to news and such thinks, just to charts, if the price is down then you can buy at low price, if the price is up you can wait for it to come down again. And then maybe in few weeks they go up like some other have do it already since few days. If you want download my bot and buy with him that coins which you like, good luck.
