For me, yes it's a good idea to invest in bitcoin and there's nothing suspicious about the $1 increase in just a month. Why? It even started with no value at all then goes up to only $0.003 after more or less 2 years and it's continuously going up through the years. From $0.003 it is now $4k+, i do believe it's possible to reach $10k after several years especially now that many establishment were using it as well.
