1. I have yet to meet anyone who has achieved financial freedom by trading Bitcoin and various other coins (let's not say you know, I've heard plenty of that), there are some who have achieved financial freedom through ICOs (but not as many as you might think, and this is only 'financial freedom', it's hard to say whether it will be freedom in the future); 2. Although trading coins makes it extremely difficult to achieve financial freedom, making some money in 2017 was relatively easy, however, the vast majority I have seen have to return where they earned from, no need to explain why; 3. There are only three categories of people who really make money relying on blockchain and have the opportunity for financial freedom: 'selling mining machines or mining, exchanges, blockchain media', there are still opportunities now; 4. Don't say I missed ICO in the third point, ICOs are not about making money, they are about financing, those who treat the financing money as their own earnings and run away end up with three outcomes: 'the country messes with you, investors mess with you, and you mess with yourself for the rest of your life', you always have to pay back when you come out to mix; 5. Pay attention! This wave of blockchain is indeed a historic opportunity for the underdogs to rise up like a peasant uprising, if you indeed have no shoes and are barefoot, it's worth a gamble; Finally, for those who have made quick money, it is indeed very difficult to settle down and do something else, from personal experience, it really feels like 'in front of blockchain, everything else is inferior', in this era and under these conditions of opportunity, it is indeed a case of 'the benevolent see benevolence, and the wise see wisdom', there is no right or wrong, only win or lose.
