All of us who invest have expectations that the market will do much better after they invest. An investor may never invest thinking that the value of the coin they invested in will drop after they invest. As you said currently the price of Bitcoin is sitting at 35 thousand dollars and from this point the price of Bitcoin can go much higher. As you have seen the possibility of the price of Bitcoin going up, as an investor I see the possibility of the market going up as well as the possibility of the market going down. We have to make investment decisions knowing that the prices of various coins may fluctuate due to market volatility.
It was a good time to invest in Bitcoin when it was $17000 and it was still a good time to invest in Bitcoin when it was $28000 and now Bitcoin is at $35000 and I think it is still a good time to invest.
As we will invest in long term plan so small change in any coin will not have any adverse effect on our long term investment. When investing one should always plan long term investment, short term investment never fulfills the desired expectations of an investor.
No one knows what will happen to the market in the future. Now the positive trend continues, after last week's increase until now market conditions still tend to be stable, and the future cannot be predicted with certainty.
To choose when is the right time to enter, I think we have our own speculation and targets, there is nothing wrong with investing at a price of more than 35k or more than that if we have a strong belief in a future where the price will be even better.
Long-term or short-term investments are the same, depending on the strategy we use, and it is true that short-term investments have greater risks, especially when Bitcoin prices are currently surging.
