We are at 30K and not at 300K that you start off thinking some other strategy:

For me, I will keep on DCA till we reach the All time High, After that i may not DCA but start to take profit slowly. But remember that 30,000$ price is not a price where one should think of taking profit. No doubt if you have been buying in previous months and weeks, you may be at a loss but why to sell at these prices which are still cheap for bitcoin, makes no sense.

If you do not have any urgent need for money, better keep holding.

Yeah actually mate the strategy should always be to keep accumulating because you cannot quit accumulating just because you saw the Bitcoin price ranging between $30k and you feel the price has gone way more than the price you normally wish to buy, but perhaps seeing the Bitcoin price $30k should have been a motivation to keep accumulating because it has become a crystal clear that Bitcoin price has beginning to peak up and the possibility of dropping back to the previous dip may not be possible, and since it has been given this positive moves shows that the possibility of the price to continue growing is possible so the best way is to keep accumulating using the normal DCA strategy to slowly accumulating consistently.

But however if you feel you have enough capital to Lump sum is also your decision to make so if you feel using lump sum will not affect your financial state you can go ahead.
