If I would yet had $0,00 in crypto, I would probably had divided all my funds dedicated to cryptos in 10 parts, then spend 1 part right now, set 4 buy orders below 6K, spread in ~ almost egual distances (every next lower may be 2x bigger then the previous), and other 5 buy orders at certain critical prices above $6K. Thus may GIVE the lowest risk entry, while agreed to be happy with not the absolute maximum possible gains and profits.
Something like this, if you decided you can spent maximum 10K :

• $10,999 buy for $1,200
• $9,999 buy for $1,000
• $8,999 buy for $800
• $7,999 buy for $600
• $6,999 buy for $400
• $6,100 buy for $200
• $5,001 buy for $400
• $4,001 buy for $800
• $3,001 buy for $1,600
• $2,501 buy for $3,000
  TOTAL dedicated: $10,000

( it is only an example for visibility what i mean, not a precize recomendation)

In case it drops to $2499, you will already have $6000 worth of BTC, so then you can easily CANCEL all the left 5 orders in the 7-11K range, and just enjoy the growth and profits
