I want to invest 5K into crypto what should i buy for short term profit?

I have invested in the past and i know how things work, but not a professional at all. Though i know when the best time is to invest and for me it’s in April.

I only want to invest in Btc or Eth. Wich one of these two will give me the highest profit short term? It is possible for Btc to go down to around 68k in april and for Eth to 1200. So what IF these prices will go that low wich one should i buy? 5k Btc or 4 Eth worth of 5k?

Thanks for any insight and advice!
