This is the right strategy, because dip will always have good things going forward,
especially if you bought Bitcoin when dip came at $ 5000, and now you have got 100% more profit from Bitcoin,
HOLD is not a terrible word.
If you are just getting into bitcoin, then you likely are not going to get any more opportunities to buy at $5k, and even 4 digits is appearing to be very slim odds.
Furthermore, if you are just getting into BTC, you might well consider that you might not even be able to get BTC below $18k... - even if the odds are way higher to be able to get BTC below $18k than they are to get BTC in the 4 digits or lower.. but if you are just getting into BTC you don't necessarily want to be greedy and to wait for dips that may not happen.
Of course, there is value to buying on dips, as OP asserted, but there is also value in making sure that you are adequately "in" BTC too, and you are adequately prepared for UP in case UP happens.. because dips may or may not happen from whatever BTC price point that we are at.. whether we are referring to $18,4xx BTC (the current price) or anticipating some future price point in which we might be figuring out our cashflow and how we may be wanting to strategize our entry into BTC, especially if we do not have any or we feel that we don't have nearly enough BTC to be prepared for possible UP..
