I definitely cant see Cindicator and ADA returning 2x-5x any time in the foreseeable future. Both have a big pump based on future expectations and no actual product/breakthrough yet.
Did you shop in some Thrift shop? Lot of shitcoins in there. Please do a proper research and check the whitepaper/ Roadmap before investing for a long term holding. Don't go by whats trending in the market but by the real world use case and the working product. Cardano is one such example where it shows. Its doesn't even have a working product and its currently in the top ten is absolutely ridiculous.
If I were you I would go for NEO, ICX, IOTA, XRB, PRL and the list goes on and on. At the end, the coins with a proper use case will be the one sustained.
Listen to this guy he knows what he is saying, though I would skip IOTA from his list as it seems to be losing steam at the moment so if a 2x-5x is your target I dont think IOTA is your go to coin for the time being.
