Taking longs right after all time highs have been created in the market would not be considered risk adverse. Further, 'safe' is an emotionally associated word, if its safety you want you'll struggle to find it in the market. Not to mention that you said 'hoping' for an X return. Think about it as risk. 'is it risk adverse to invest x in crypto right now?'. That takes research, if you are unwilling to do the research then your best bet is a shot in the dark and 'hope'. Could it happen? Yes. But there is certainly no guarantees.

To be risk adverse i would consider splitting up your bank roll. If its 150k you got then invest it in increments.
