it depends if you expect btc to go down a lot from here.. if you think its a bottom then its a good time to buy mex or at least hodl for better prices

This would be so nice but sadly not how the crypto market works. Right now they play the volatility downtrend game going sideways at times, letting people slap on leverage only to take the money either way. All this sneaky liquidating funds higher highs. The secret to crypto has always been buying the top assets and just staying hodl with them. All of this and add the halving schedule as well for a pretty good view of the way things work...

If you take what you want to invest and divide it in 10 parts you can buy 1 part of it every week for the next 10 weeks. If it dips to your price target you could decide to buy 2 or even 3 times your weekly budget. This way you get a great price overall. Sometimes you buy a bit expensive other times cheap but in the end youll have a solid price when you put it all together
