Bitcoin is always the best currency to invest in. If you invest in Bitcoin now, you will forget about that investment for some time after the investment. And only keep an eye on bitcoin price when it crosses 100k, because we all know and believe that bitcoin price will definitely go above 100k. If you look at the Bitcoin price chart for the last few days, you can see that the price of Bitcoin has increased amazingly in the last few days. So you invest and hold without panicking. And never think to selling.
The thing is that if we rush and invest when price of bitcoin increase to 100k as you said, thinking that the price will continue to increase, it's a wrong plan, anyone who invest to make instant profit in bitcoin I think that person is mistaken, we have to know that we need to hold our bitcoin for some long distance so that we can make a reasonable profit from cryptocurrencies investment, we need to understand such thing first before we invest, hold your bitcoin whenever you invest on it.
