Any sane person with knowledge or who has set out to broaden their horizons and make investments can invest.

No need even advising people, everyone knows before joining the cryptocurrency that they are risking their fund and why most wise people will make investment on the amount they can afford to part ways.

Yes I agree.  One should  not invest all his wealth in crypto currency or bitcoin.  Only that part of savings should be invested that are surplus with him.  The reason being appreciation or deprecian in the price is not certain.  Market may fluctuate either ways.  So if we invest our savings in it we may have to suffer huge loses.  and our funds may be blocked. 

that's right bro. therefore I always set aside some of my money for daily needs. and for savings if there is a sudden need. while the price of bitcoin is still down as it is now

I agree with you that you shouldn't invest all in cryptocurrency. Never, never break the golden rule of investment: Don't put all your eggs in one basket; otherwise, you might end up trying to commit suicide. We all know for a fact that cryptocurrencies are virtual, meaning they do not represent a material thing. It's rising in value, because there is a mania of turning it into a big lottery. Speculators are the only people driving up the price. But what if the frenzy dries up the value and evaporates consequently? You have lost all--money, time and energy. Even the crypto leaders did not fail to to warn us about crypto bubbles. So better be safe than sorry. Invest in crypto now, yes, but not all. Never invest more than you are prepared to lose.

I do not think he can put all the wealth he has to invest in bitcoins. That is a wrong decision. I think he was in a hurry to invest all that money into Bitcoin without looking into it. And now that most of the crypto market is falling, will he be happy and want to sell the bitcoin he has invested? I hope he does not. Once you have determined your investment in this market, the most important factor is your perseverance, or knowledge of the market that determines whether or not to invest.

Crypto is a risk business, I don't think too much about loss as long as you know your steps are right, but don't ever throw your money for crypto because it's just a fool who invests money in one business. try to explore deeper into what the crypto world is so it's not wrong to make choices

If somehow the investments are in different cryptocurrencies  and research was done and the willingness to take the risk to gain or lose is there. Indeed it is admirable.Investment is not increase wealth. So what it goes lower than this, such owner might get shocks in his/her body. Digital currency is good but wisdom is also demanded.

It seems to me that the people who invested all their savings in bitcoin were when it began sharp to grow to 20 thousand dollars. On that wave of high prices many hoped that this will continue forever and the cost of bitcoin will only increase. Now, it seems to me, people approach this issue with greater caution. They invest more intelligently, although I can't affirm this.

Investing all you have in bitcoin or cryptocurrency is so risky, for me maybe that is the worst decision in my life, if ever I will do it, I will not put my future in the things that I am not sure what will happened.
