How safe is it?
According To me Its Not Safe to Invest Your Money Into Bitcoin For Long Term Because Bitcoin Price is Not Stable And You Can Lose Your Whole Capital If the Price Crashes.....
According to me Instead Of Investing Your Money In Btc For Long Invest it For Short Term So You Can Hope To Make Some Profit.....
that's not true. you don't lose anything if you don't sell any of your coins. that's something that a lot people don't seem to understand. people have different investments. one for the long term, one only for trading, etc. via that way you can benefit in the short term, but also benefit in the long term if the price indeed happens to go up a lot.
Yes and its good to use them in both ways also in short term and in long term, as only holding all of them will not serve the purpose you also try to grow them by investing or with trading.
