Just like the very first posts says? this is experimental and we can really tell when it happens .
Coinmarketcap or any exchange cannot help you because this is the task that obligatory for us to find because it is our funds that will be at risk here.
Buy only a currency that you can afford to lose.
and yeah Put 100 dollars in each cheapest coins and see what happens in the next 5-10 years .
This isn't experimental. Bitcoin and similar coins have already done an explosion on the past for a lot of time and those people that invest on them are sure on why they pick those coins. It can only be called as experimental if you invest on the meme coins because their future are unpredictable but if you are lucky you can get the multipliers that are seen in the title of this thread.
Coinmarketcap is helpful for our analysis because it displays every coin's data and they have warnings too to tell if a coin is shady or not while an exchange only helps you to make an order (buying and selling cryptos). The rest of the work will depend on us.
