If you know what you are doing and have a knowledge then do trading and you knoe that there's a risk and chance of losing your money and not just double but triple your profit if you have bougt the right and timing to trade.
That's why you need to research on which is the best crypto to buy or do trade to make a lot of profit and also depend on how much money you will invest.
This kind of thinking is what gets people in trouble, they believe that they can make that kind of money in a very fast way and that is simply not true unless you are willing to take ridiculous risks that will most likely make your strategy look a lot more like gambling than any investment strategy, it is simply not possible to double your money while taking reasonable risks and anyone that thinks so should leave this market because this market is not really for them.

Despite what newbies say in this thread, the answer is NO, it is NOT POSSIBLE (not a ghost of a chance) that u double your money within a 2-months term. It sure depends on what your capital is (if all u got is $100 then yeah u could probably double that in 2 months), but if we were to assume that u have >$50k to start with, then no it is very unlikely that u could run it into $100K after 2-months period. I hold at least 3 coins long-term... And I have recently put close to $90K in 10 binance shitcoins, and guess what, I am down on all fronts. Its called bear market, boy. Regardless of what u buy, u are poised to endure losses, both medium- and long-term. Most binance alts are moved all at once... by a fat market maker or by CZ himself... and every single one has lost a share against bitcoin. Doubling your money would have been possible 2-3 years ago when alts had more independence in their moves and were less reliant on a global (and hugely artificial) trend we see now. Sadly this is not possible in this market. For now. 
Sorry but you have no idea what you are talking about. Someone winning on a lottery (being early adapter of BTC or ETH for example) does not equal to this being a regular possibility and repeatable on regular basis.
