First let’s start with a normal investment that is not Cryptocurrency like gold and bonds and the rest of them – you know very well that none of these that are considered legit will fetch you up to 100% in a year right?
If you invested in bonds, in a year your highest profit will be 12% , so if you invested that 500 dollars in there you’re going to be getting extra 60 dollars making it 560 dollars in total. Then you come to cryptocurrency and you’re able to double that money from 500 dollars to 1000 dollars, that’s more than enough, you can withdraw the extra 500 dollars you have got and the rest can be left in the market since it’s now like free money that you’re investing with, and if you’re lucky the market will still increase.
True, but not quite true. If the investment is in the right asset, it may be profitable. But if it's in shitcoin, that's what they get. Timeliness, momentum, and selection of the right asset will determine the success of an investment. Not all cryptocurrencies are profitable, some of which can hurt trader and investor.
It became the right on if you're just smart enough on your decisions and that might be quicker or random state. Altcoins has no assurance, because you should be selective on those coins that has sustainable value. Potential profit will follow once you belong to the project that has strong roadmap plans, but if it only ride with the hype I don't think it will be successful.
