I am investing Bitcoin today even if the price is still very high and risky. I still believe in some speculation that btc will rise up to 100k$ before the year 2021 end, that is why I buy some Bitcoin and hold it till the price reach up to 100k$ may I know what are you thinking this time is it a Time to buy or hold or what ?
You are investing with very high risk amount and actually I would advise that currently BTC price is hitting a high level in the very hard to invest zone and today it is becoming more and more difficult to invest in BTC . You need to think carefully because you will most likely be manipulated or emotional when the price of BTC goes up and down . Losses are very likely to happen this is just my sincere advice and investment or not is up to you to decide.
The OP's aim of achieving $100k this year may not happen but maybe he can still gain profit based on his buying price. Though bitcoin is a much better investment as compared to these meme tokens or new alts without use case, but still the OP should consider the risk involved also.
