I think at the moment, It is a good idea to invest in the coins second generation like Ethereum, Lisk, etc.
Since more than a year I keep an eye on the next ICO/IPO/crowdfunding. I've never lost any money in it and sometimes, it is relatively easy to multiply the initial investment by x10 or even much more (Ethereum for example).
I agree on it, i also use to trade some alt coins.but my plan to get rich is invest or make money on trade then invest on some legit crypto currencies,like leo coin, wowecoins. And otger companies outside .just like mlm .but i will use bitcoins to paid.
