Those who think the blockchain and crypto market will be a lot higher can simply buy in and HODL. Yes you will go through ups and downs, but the attempt at timing the market is removed. This is a valid approach if one things that blockchain is a technology that will be implemented a lot more in the future.
Good suggestion. Are you an all in kind of person? Buy once and forget?
Personally, I can't do it. It's not my style. I like to average myself in. Just buy gradually at intervals. I use the same tactic for bottom finding.
I am a buy and HODL. I dont go all in at once but do add as fiat allows me to. I do cost average. My STEEM purchases range from $.80 to $1.30 with one batch at $2.
My BTS ranges from $.05 to $.30.
I did that with my holdings in LTC, BTC, and ETH although I lightened up on those three a while back.
That is just my approach....I guess need to have a long term optimistic outlook about cryptocurrency and the blockchains buying into.
