Realy realy bad idea putting your life savings into 1 plan, mining is hard and expensive unless you can get free or nearly free electricity and broadband. Personally I would not put more than 20% of my savings into anything-just imagine how it will feel if you loose all you have worked so hard for for so long, By all means reinvest your profits back into crypto and with luck you will see a big capital gain.
after learning many things about crypto and blockchain I dare to give my savings up to 30% for crypto. crypto is a modern financial technology and has many advantages over its lack, when people realize that all crypto have fantastic prices and we will regret not investing
I think 30% is enough to invest in cryptocurrency because you still save the other money for your daily needs and I think this can work well for you especially if suddenly, all of your coins are getting an increase so you can make a big profit. and from 30% of the investing, you can diversify to many coins and you can buy a lot of amount from each coin and I am sure that it will give you a nice profit in the future.
