It is very unlikely if you didn't invest at least 10k usd. I'm talking about nowadays, not beginning of 2017. Very difficult to find a coin with 1000x return and hodl it. Like if your coin is 0.001 now and after 1 year is 1 usd. But if you invested like 5 bucks and got 5k coins, you'll end up with a nice sum, but not nearly as a million. But invest 200 usd, and you're the millionaire. But you must be a lucky champ for that. More realistically you'll invest 200 usd for each of 20 promising coins and bingo, ur the millionaire!
Its unlikely but not impossible. In fact you can make real wealth trading crypto.
With NEO, I bought 500 shares at 30 cents or so, and sold 90% of the shares and missed out on some of the upside. I pulled out 1.3BTC from the sale of 90% of the shares. Its not wealth but not shabby either.
With Reddcoin I bought 10M shares at an average of 5 sats and sold most around 70 sats in the summer of 2017, I didn't get the highs in Reddcoin which occurred in December 2017, but the profit was sizable. Ideas that have worked for me
1. low market cap of the coin, preferably below $1M or $30M when you initiate the trade
2. make sure the coin has decent technology, what do experts say about the coin? need activity on github, solid white paper, etc
3. make a sizable bet when you have conviction
4. pull out some of your profits
