For sure, it is likely that we can recognize and appreciate anyone who might have gotten involved in BTC 7 years ago would be sitting quite pretty right now, even if they might have done so in a DCA way rather than lump summing in.. .. DCA'ing at
$100 per week would have had resulted in $36.6k invested and around 6.35BTC; however since the BTC price was less than $1k in late 2016, lump summing would have gotten more than 36.6 BTC for the same amount spent.. So method of investing sometimes will depend upon whether funds are available.
In regards to your explanation, this is diagram I arrange that shows the Statictistic of of applying DCA method at $100 each week 7 years ago but found out that would have even made a huge sum of BTC within the shortest period of 6month is early 2016
Month/year. BTC price/low. BTC price /high
1/1/2016. 354.91. 462.93
1/2/2016. 367.96. 448.05
1/3/2016. 394.04. 439.65
1/4/2016. 415.83. 467.96
1/5/2016. 437.39. 553.95
1/6/2016. 525.64. 777.99
This my analysis on DCA strategy of January 1 2016 to June 2016 in respect to what you presume of making up to 32 BTC in 7 years back I think it can be even more than. because judging from this my table I think DCA can give up to 20btc within this shortest period of 6month talk more of 7 years probably it might be more.
Bitcoin price is moving up gradually and if you know that you are interested for investing in bitcoin I believe this is the normal time we can invest in the bitcoin, so their no time we invest that is waste of time but the problem is to know when is dip so that you will make a profit in cryptocurrency investment, things I know of bitcoin is that we are not supposed to be believing in the speculation of bitcoin because speculation is one of the things that makes people to invest when they are not supposed to invest in bitcoin
Are you buying in dip to make profit in a short time or buying dip to accumulate more. Well it's up to you. But I think dip is an advantage to you to aquare more no time is too late because you might think #35k is too high to be called dip probably tomorrow you regret why not buy at $35k as dip compeard to when the price might have been maybe #40 to $50 or so.
