Short term is almost always a gamble regardless of what asset you buy. You could literally buy the best stock or the next best performing cryptocurrency of the year but you can still end up losing when talking about a short timespan.

Like holding bitcoin for at least six months to a year is what is known as the short term investment. Do no mind I use bitcoin and not mention any altcoin.

I will prefer to invest in bitcoin.

Best to wait and let bitcoin fall to around $30000 to $35000. Then you can invest. Short term may not be accurate, the price of bitcoin may not fall to that price, it may fall to the price, anything can happen.

The best is to have long term investment strategy, thinking of 4 years or more. With this, you can even buy bitcoin now, wait for ATH. After next halving, bitcoin may reach six digits. Bitcoin ATH was $69000, the price is at $42500 recently, that means there are corrections already, a good time to invest but on long term.
